525.620.8VL - Electromagnetic Transmission Systems

Expanded Course Description

The Fall 2022 term is being taught by a substitute instructor, Daniel Jablonski.  The grading rubric, policy regarding assignment due dates, and the manner of considering tests and quizzes will be modified for this term only, so as to increase flexibility during Fall 2022.  Adjustments for this term will be shared with students via online Canvas announcements and during real-time lectures (which will be recorded).  The material will be that used in previous terms, with the addition of supplemental information to compensate for the lack of a textbook.  It is assumed that students have prior knowledge of electromagnetics, and likely a general purpose electromagnetics text.  Students are always able to request references and/or supplementary material to fill any gaps with respect to textbook style information.

Course Structure

We will use the existing online course materials, assignments, quizzes, and tests.  However, the quizzes, tests, and exams will be regarded as assignments, not assessments, for this term (Fall 2022) only.  Students can use the discussion forums, with proper acknowledgement, for quizzes and exams, for this term only.  The weighting factors for exams and quizzes will be developed early in the term, once it is possible to assess the backgrounds and concerns of students.  Use of the discussion forums to ask, suggest, etc. about content and assessments is encouraged.

Course Topics

The material begins with a review of electromagnetics (and electrostatics).  Transmission line theory and discussion of the properties of the most prevalent transmission line techniques will follow the order of the online modules.  

Course Goals

Goals: to derive and use for computation the Maxwell equations' boundary value and initial value constraints.  Students will be able to describe and utilize the unique features of the several transmission line systems that are covered in the course.

Course Learning Outcomes (CLOs)

• You will learn the nomenclature and specification parameters of many different transmission line systems, such as twisted pairs, metal waveguides lumped element transmission lines, and coaxial cables.

Textbooks

Not required.  Supplemental material will be provided.

Required Software

Students will have access to MatLab, under the student license agreement with Whiting EP.  Other software packages, such as Excel, Mathcad, etc. can always be used, and circuit simulators (e.g., LTSpice) can be used as desired.

Student Coursework Requirements

Assignments, and exams and quizzes presented for this term only as assignments, will all be given equal weight.  Late submissions will not be penalized, so that students can ask questions of general interest in the weeks after an assignment has been made accessible.  The goal here is learning, taking into account the wide variability of student backgrounds.  If students have accessibility challenges, are on travel, or have family obligations, accommodations will be provided.  For ADA related accommodations, consult the appropriate Whiting EP contact, provided elsewhere.  

Grading Policy

Grasing of assgnments for this term only are on a basis of 0 - 10 points per assignment.  8 is considered an A performance, with a numerical grade of 10 equal to an A+.  6 means a grade of B, that improvements can be made, and resubmission of all or part of the problem is encouraged.  A grade of 5 means that an assignment has been submitted, but is a grade of B-.  A 0 means that no assignment has been submitted.

Course Policies

If work or family circumstances arise, it is not urgent to notify the instructor.  These situations are commonplace, and can always be dealt with with no need to fret over grades.  The goal o f the course is to learn, and enjoy doing so.

Academic Policies

Deadlines for Adding, Dropping and Withdrawing from Courses

Students may add a course up to one week after the start of the term for that particular course. Students may drop courses according to the drop deadlines outlined in the EP academic calendar (https://ep.jhu.edu/student-services/academic-calendar/). Between the 6th week of the class and prior to the final withdrawal deadline, a student may withdraw from a course with a W on their academic record. A record of the course will remain on the academic record with a W appearing in the grade column to indicate that the student registered and withdrew from the course.

Academic Misconduct Policy

All students are required to read, know, and comply with the Johns Hopkins University Krieger School of Arts and Sciences (KSAS) / Whiting School of Engineering (WSE) Procedures for Handling Allegations of Misconduct by Full-Time and Part-Time Graduate Students.

This policy prohibits academic misconduct, including but not limited to the following: cheating or facilitating cheating; plagiarism; reuse of assignments; unauthorized collaboration; alteration of graded assignments; and unfair competition. Course materials (old assignments, texts, or examinations, etc.) should not be shared unless authorized by the course instructor. Any questions related to this policy should be directed to EP’s academic integrity officer at ep-academic-integrity@jhu.edu.

Students with Disabilities - Accommodations and Accessibility

Johns Hopkins University values diversity and inclusion. We are committed to providing welcoming, equitable, and accessible educational experiences for all students. Students with disabilities (including those with psychological conditions, medical conditions and temporary disabilities) can request accommodations for this course by providing an Accommodation Letter issued by Student Disability Services (SDS). Please request accommodations for this course as early as possible to provide time for effective communication and arrangements.

For further information or to start the process of requesting accommodations, please contact Student Disability Services at Engineering for Professionals, ep-disability-svcs@jhu.edu.

Student Conduct Code

The fundamental purpose of the JHU regulation of student conduct is to promote and to protect the health, safety, welfare, property, and rights of all members of the University community as well as to promote the orderly operation of the University and to safeguard its property and facilities. As members of the University community, students accept certain responsibilities which support the educational mission and create an environment in which all students are afforded the same opportunity to succeed academically.

Classroom Climate

JHU is committed to creating a classroom environment that values the diversity of experiences and perspectives that all students bring. Everyone has the right to be treated with dignity and respect. Fostering an inclusive climate is important. Research and experience show that students who interact with peers who are different from themselves learn new things and experience tangible educational outcomes. At no time in this learning process should someone be singled out or treated unequally on the basis of any seen or unseen part of their identity. 
 
If you have concerns in this course about harassment, discrimination, or any unequal treatment, or if you seek accommodations or resources, please reach out to the course instructor directly. Reporting will never impact your course grade. You may also share concerns with your program chair, the Assistant Dean for Diversity and Inclusion, or the Office of Institutional Equity. In handling reports, people will protect your privacy as much as possible, but faculty and staff are required to officially report information for some cases (e.g. sexual harassment).

Course Auditing

When a student enrolls in an EP course with “audit” status, the student must reach an understanding with the instructor as to what is required to earn the “audit.” If the student does not meet those expectations, the instructor must notify the EP Registration Team [EP-Registration@exchange.johnshopkins.edu] in order for the student to be retroactively dropped or withdrawn from the course (depending on when the "audit" was requested and in accordance with EP registration deadlines). All lecture content will remain accessible to auditing students, but access to all other course material is left to the discretion of the instructor.
