Thank you sir this was extremely helpful , because before tackling any subject , I shall know the reason why it's useful, and this made it happen

So, I am someone who graduated from college in 2019, and now I am back in masters after almost 5 years, I must say I really really wish I had access to such wonderful content and resources back when I was in school and in early years of my undergrad. This is pure gold.

Did he just explained it better than Mr. Feynman himself. I truly appreciate it. I was looking up in Feynman lectures to understand waveguides, a bit confused and searched on KZfaq to find yours. And it's incredible.

I'm also new in photonics, I did my undergrad project about tapered fiber, and now i'm pursuing my studies in Bath, UK, also in the same field. You helped me alot in understanding the real concept of waveguide. Thank you so much!

hy, Thanks for your help.I would like to ask you one question about waveguide & electromagnetic radiations in Radar. ->> When we generate an RF signals >>then we amplifier , before the signal enter the waveguide: Here is the signal electromagnetic or analogue: If analogue where to turn to electromagnetic. If electromagnetic dose waveguide responsible for converting analogous to electromagnetic signal

@JordanEdmundsEECS 2 жыл бұрын

Everything is an electromagnetic wave. When the dimensions of the stuff involved is really small compared to the wavelength, we call it a "circuit" and we call the signal an "analog signal". When it is well-contained in a particular waveguide or circuit, we often call that an "RF circuit". When you send it to an antenna, because the antenna dimension is large, we call that an "electromagnetic wave" (and antennas are usually designed so that they radiate well).

What about lithographing at the 10NM level hundreds of thousands or millions of holographic waveguides on a silicon surface? You could create a light transistor. The incident light could be tuned to any angle by adding bias to the silicon wafer using increased concentrations of germanium by altering the refractive index.

what is the relationship of frequency and attenuation?

@ericphan5857 2 жыл бұрын

That is the problem it should be 1/ π^2 and π change as speed of light change over ether and space-time. So π is changing and R always =1 represents the source

@bennemann 4 жыл бұрын

Fantastic video, very instructional, thank you! The only part that confused me is how you said that where Alice shouts into the waveguide matters (top vs. bottom vs. center), but then shortly after you say that the ONLY thing that matters is the frequency of the wave. So it was contradictory there.

@JordanEdmundsEECS 4 жыл бұрын

Ah, my bad, let me clarify. Both things definitely matter. Where Alice shouts into the waveguide matters for how much of her voice gets inside, but once it’s inside all that matters is the frequency (loosely speaking).

Is a parabolic shape reflector a waveguide ?

@JordanEdmundsEECS 2 жыл бұрын

Great question. A parabolic reflector usually takes light from far away, and sends it back far away (reflects it), so I wouldn't consider it a waveguide, because it isn't "confining" or "guiding" the light. It's more like a "waveshaper" than a waveguide.

can you explain how you got 4*10^-10 at 7:02? I’m trying to do the calculation and not getting the same result. Thank you

@KISHORENEDUMARAN 3 жыл бұрын

Hey, I hope you figured this out, but here's how I think he got 4*10^-10. Area of hemisphere, ignoring ground = 2πr^2 = 6300000 m^2 Area of his ear, considering as square = .05*.05 = .0025m^2 Attenuation = Area of bob's ear/ Area of hemisphere = .0025/6300000 = 3.96*10^-10 ≈ 4*10^-10
