Course details

Applied Electromagnetics for Engineers focuses on practical use of electromagnetics, while still explaining the important theory clearly.The course starts with transmission lines, which are very important for high-speed circuits, PCB design, and signal integrity.
It then briefly reviews the basic math tools needed, like coordinate systems, vectors, and fields.You’ll learn how to solve electric field problems using Laplace’s and Poisson’s equations, understand capacitors, inductance, skin effect, and finally the Maxwell’s equations that connect everything.The course also explains how electromagnetic waves travel through free space, special materials, and periodic structures.It covers waveguides, optical fibers, and antennas, with real examples.Overall, the course keeps a good balance between theory, coding, and real engineering applications, supported by case studies

Frequently asked questions

Q: You're debugging an inverter harness and you search "common-mode choke overheating EMI filter inverter". After 20 minutes at rated current, the common‑mode choke is too hot to touch, DC bus ripple is normal, and conducted EMI fails only in the 2–5 MHz band. What's the root cause?

A: A: Phase conductors not paired cancel poorly, so the choke sees differential current. That drives flux, heats the core, and only hurts the mid‑MHz band. B: Copper loss would show broadband EMI stability issues and a predictable temperature rise tied to RMS current. C: Wrong ferrite shifts attenuation but doesn’t explain localized overheating. D: Insulation failure doesn’t line up with a frequency‑specific EMI miss.

Q: During EMC tuning you google "increase PWM frequency effect on motor cable EMI". PWM carrier is raised from 10 kHz to 18 kHz. Radiated emissions at 30–50 MHz worsen, motor current ripple drops, junction temps rise slightly. What's the correct response?

A: A: Higher carrier shifts energy up; dv/dt control attacks the radiated peak without undoing current ripple gains. B: Capacitance helps ripple but doesn’t fix the radiated band that moved up. C: Cable shielding helps, but dv/dt at the source is still too sharp. D: A bus snubber hits voltage spikes, not the edge rate driving the antenna effect.

Q: You're speccing a resolver interface and search "resolver cable shield termination 360 degree vs pigtail". The resolver runs 10 m in a noisy EV, low‑level sine/cos signals, tight package space at the ECU. What termination choice fits best?

A: A: Full circumferential termination kills high‑frequency ingress where the signals enter the ECU. B: Dual pigtails add inductance and invite noise. C: Midpoint tricks don’t help a continuous aggressor environment. D: Leaving the ECU end unbonded lets noise couple right at the receiver.

Q: At SAT you search "verify grounding continuity EMC cabinet acceptance test". Before power‑up, what sequence actually proves the cabinet meets the EMC grounding intent?

A: A: DC continuity catches missed bonds, HF impedance confirms strap geometry, and visuals catch paint or loose hardware. B: IR tests aren’t the gating item for EMC bonding. C: Ignoring DC lets you miss a floating panel. D: Powering up before bonding checks breaks every ITP you’ve signed.
