Grading recipe (no make-ups are offered, except in cases of documented medical or family emergency):

— See also the minimal requirements for passing the course —

The goal of this course is to explore the details of electrodynamic interactions, continuing the topics covered in the prequel (Electromagnetic Theory I). To this end, we will discuss the Lorentz-covariant formulation of electrodynamics, the interaction of the electromagnetic field with charged particles in motion. We then focus on specific configurations and arrangements, involving: (1) electromagnetic waves in nonconducting media, cavities and waveguides, (2) the multipole expansion of electromagnetic fields, radiation, scattering and diffraction, and various radiative processes. The course finishes with a brief review of electrodynamic feedback and the classical models of charged particles.

Minimal Requirements

To pass the course with a grade B or better, a graduate Student must by the time of the final exam be able to demonstrate the ability to determine:

1. the relativistic motion of charges in static electromagnetic fields, and the lowest-order relativistic corrections;
2. the reflection and refraction of electromagnetic waves near plane interfaces between two uniform media;
3. electromagnetic wave propagation in wave-guides and resonant cavities;
4. the electromagnetic wave characteristics near radiating systems and far from them;
5. the scattering of electromagnetic waves in simple media and from simple objects.

A graduate student who cannot demonstrate the above listed skills by the time of the final exam automatically forfeits a grade of B or better — regardless of the total number of points acquired in homework, quizzes and exams.

All written assignments (HW & take-home tests) are due by 12:00 am (midnight), end of the day indicated and should be sent by e-mail as single (bundled) PDF files; to this end, using a camera-to-PDF-scanner app on a smart-phone or tablet is highly recommended. Late homework will not be accepted, except in cases of documented emergency.

Other Matters

Collaboration Policy

Collaboration — but not blind copying — on the homework assignments is strongly encouraged; students should use this to learn from each other. There is no substitute for the diverse previous experiences and wealth of knowledge brought together by a cohort of students. All exams and quizzes are open text and open class-notes (including notebooks and class handouts), but no collaboration is allowed; by signing and submitting the exams and quizzes, the student vouches to have abided by this policy. Violation of this policy is covered under University regulations on academic dishonesty and cheating.

Presentation and Organization

First and foremost: your assignments are your communication to the instructor of the level of expertise to which you have mastered the subject matter covered in the course. So, while a neat presentation of home,- quiz- and exam-work is not required for full credit, it certainly makes it easier to assess the quality of the work and give the proper credit due. In all cases, include a simple sketch if it might help conveying the approach or the calculations. Where necessary, include all units and symbols such as the measure of an integral, arrow on a vector, vertical bars for the absolute value of a quantity, for the magnitude of a vector or for the determinant of a matrix, etc.

• Homework: Submitted answer sheets should be bundled. The Student’s full name (and ID number) should be indicated on the first (cover) page. Solutions should be labeled and ordered consecutively by the problem numbers. Include all calculation/work and give full reference to any result quoted from any source other than the text, and page/equation number for results quoted from the text. Homework assignments will be graded by a grader with whom unsatisfactory credit should be disputed prior to appealing to the instructor; the instructor may override the grader’s assessment.
• Quizzes: The Student’s full name (and ID number) should be indicated on the first (cover) page, unless otherwise requested at the time of the quiz. Include all calculation/work and give the page/equation number for results quoted from the text. Speed and efficiency is important, but the presentation must be legible.
• Mid-term exams: All exam questions are given on a question sheet and include the detailed point distribution and the place to write in the Student’s full name and ID number. This question sheet is to be affixed on the top of the answer sheets; it will be used to indicate the acquired points, part by part and in total, the average score and the standard deviation. A second copy of the question sheet is to be used for the take-home part in the same manner. The formula by which the points will be summed between the two parts will be given on the question sheet.
• Final exam: All exam questions are given on a question sheet and include the detailed point distribution and the place to write in the Student’s full name and ID number. This question sheet is to be affixed on the top of the answer sheets, in the top-left corner. It will be used to indicate the acquired points, part by part and in total, the average score and the standard deviation. The final exams are stored by the instructor, but are available to the individual student for review after the exam.

Each assignment is to be submitted (and is date-stamped) by e-mail (→ thubsch@mac.com), as a single PDF file. Handwritten and other “hard-copy” answer-sheets should be scanned and bundled into a single PDF file — there are many smartphone and tablet apps that do this automagically; some printers also include a flatbed scanner, if you prefer.

University Attendance Policy

Class Attendance Restricted to Registered Students: Only students whose names appear on the official course roster are permitted to attend class meetings. Students who are not registered are not permitted to attend or participate in course activities, do not have access to Blackboard, cannot submit course assignments, and will not receive a grade for this course. It is the students’ responsibility to ensure that they are properly registered by the published registration deadline. Requests to add courses after the deadline will not be considered.

ADA Procedures

Howard University is committed to creating an accessible, inclusive, and safe learning environment for all students and providing equal access to students with documented disabilities. Students seeking reasonable accommodation must first register with the Office of Student Services (OSS). There you can engage in a confidential conversation about the process for requesting reasonable accommodations in the classroom and clinical settings, which the Office of Student Services (OSS) determines. Accommodations must be requested each semester. Accommodations are not provided retroactively. If you want to request accommodations, please contact OSS via email at oss.disabilityservices@howard.edu or visit https://howard.edu/disability-services
