Help Sessions for Apr. 6–10 (4/5/2026)

I plan to be available at least at the following times this week.

  • Monday 5:00–5:45 pm (BRKI 368)
  • Monday 10:00–10:45 pm (Zoom)
  • Wednesday, 3:00–3:45 pm (BRKI 368)
  • Wednesday, 5:00–5:45 pm (BRKI 368)
  • Wednesday 10:00–10:45 pm (Zoom)
  • Thursday, 4:00–4:45 pm (BRKI 368)
  • Friday, 2:00–3:45 pm (BRKI 368)

I am usually available for short consultations on Mondays, Wednesdays, and Fridays at 4:50 pm in BRKI 264 or in my office.

Guidelines and additional information:

  • Please contact me if you have a conflict with these times and would like to schedule a meeting at a different time.
  • The Zoom link is available at the course Moodle site.
  • If I am helping another student when you drop by, you may usually join in the conversation.
  • If I have been helping you for a relatively long time, I might pause our conversation to help other students who are waiting for assistance.
  • For in-person sessions, if I have finished helping you, please move out to the hall or somewhere else so that the chairs in my office are clear for newly arriving students.
  • As a courtesy during Zoom sessions, please use your camera.

Reading Assignments for Apr. 6–10 (4/4/2026)

  • M: Sections 6-1 and 6-2 and the supplemental reading "The Small Loop Antenna"
  • W: Supplemental reading "The Small Loop Antenna"
  • R: Sections 7-0 through 7-2
  • F: Sections 7-2 and 7-3 and the supplemental reading "Proof of Mutual Orthogonality of the Electric and Magnetic Fields and Direction of Propagation for Plane Waves"

Section 7-0 is the introduction to Chapter 7. The first supplemental reading provides information on calculating the radiation resistance, loss resistance, and input inductance of electrically small loop antennas. Although the text is somewhat advanced, most of it should be accessible to you. We will not cover all of the material in the supplemental reading in class.

Poynting Streamline Paper (4/4/2026)

A copy of a paper that appeared in the Feb. 2024 issue of IEEE Antennas & Propagation Magazine that illustrates how the Poynting vector of an incoming EM wave is altered by the presence of an antenna is now available at the course Moodle site in the Supplemental Readings section. The paper provides visually oriented representations of the concept of effective aperture. It was discussed in class on Friday, April 3, but it is not required reading.

Review Sheet for Exam #3 (3/31/2026)

The review sheet for Exam #3 is now available on the Exams page.
