This is honestly one of the best series and explanations I have listened to and watched. You have great ability at making seemingly complex topics lucid and comprehensible. I look forward to more in your series on electromagnetics and I think you have some great potential at really striking it big with these because they're absolutely top notch.

Hey, Dr. Leigh. Thank you very much for this quality content. We need more of it! Very useful when you are a bit rusty on these topics. Cheerio!

Very good work. Your explanations are clear and concise. These videos will please to engineers. It's difficult to explain the S parameters to electronic engineers.

not exactly get the “simple circuit analysis”, as I understand, you use KVL, where you find the current looking from port 1: which is V1 divided by Z1 + Z2||(Z3+Z0), and from port 2: V2 divided by Z2||(Z3+Z0), and I have no idea, why do you multiply the right part of this 2:03 equation by Z0/(Z3+Z0)

How can I calculate the S parameters of a quarter wave transformer?

@charliebe.2082 Жыл бұрын

Z0 depends on Z1, Z2 and Z3. To be matched: Z0 (the one on the right hand side) has to be Z3 + Z2 || Z1, provided the source is an ideal voltage source. Or am I wrong?

@emviso Жыл бұрын

Z0 is the characteristic impedance at the port - the ratio of voltage to current in the outgoing wave. It doesn't have anything to do with the internal resistors.

@@emviso Thanks - got it! I was conceptually wrong.

what is the characteristic impedance of a port?

@emviso 2 жыл бұрын

The characteristic impedance of a port is the characteristic impedance of the connector (maybe an SMA connector, like this: fieldcomponents.com/sma-male-to-sma-female-connectors-rg178-cable-assembly.html) that is attached at that port and allows you to input and output signals from the system under test.
