Lecture -- Scattering from a Dielectric Slab
HTML-код
- Опубликовано: 18 апр 2024
- This lecture illustrates, explains, and derives the equations that calculate reflection and transmission from a dielectric slab. There are an infinite amount of waves present inside the dielectric slab due to waves reflecting from both sides of the slab. The concept is generalized to account for loss and angle of incidence.

I watch your videos for entertainment because the explanations are so good
Very illustrative video!
Thank you!
Excellent video! Z-phase hexaferrite from Transtech has a permittivity=permeability=10 whose characteristic impedance is matched to air (both are 377 Ohms), but the Brewster angle begins to narrow and I'm finding the bandwith of antennas are narrower vs. the same antenna in air/FR4. I'd love to see an analysis of this situation! Thank you for your most excellent videos!
Great to know! My experience with these types of materials is that they are expensive, temperature sensitive, lossy, and highly dispersive (i.e. properties change abruptly with frequency). I don't know specifically about this one. In general, mu=eps materials are very interesting!
@@empossible1577 Z-Phase Hexaferrites are not dispersive or lossy but they are very expensive! Reflection losses are minimized by matching the characteristic impedance to air, but the Brewster angle gets closer to 90 degrees. There are other materials which have much higher indices of refraction with permittivity=permeability at low loss which have recently published. We're able to shrink an antenna/lens by a factor of 10 to 20 while maintaining high efficiency and soon at low-cost!
Kindly make a video on the EDC Effective Dielectric Constant method.
I am not entire sure what you are referring to. I do have some notes on homogenization of metamaterials, also called parameter retrieval. The notes are newer than the video. See Lecture 5d in the "21st Century Electromagnetics" class:

@@empossible1577 Thank you for your response. I will go through the referred notes. Actually, I was searching for videos on the EDC (Effective Dielectric Constant) method so I request you to make a video on this topic.
