Personally, I'd sooner resort to voluntary euthanasia than Maxwell's equations.

Spot on. Robin, G8DQX

I was taught that when the circuit size exceeds about 1/10 wavelength, Kirchoff's voltage and current laws as they are near DC representations of Maxwell's equations no longer hold, and you need to

As I teach my college students: there is NO difference between Audio Frequency AC math and so called "Microwave" math. It all about the circuit models. Wavelength is the issue for what is important.

I was considering the way it was handled as time went on.? I have a copy of a 1952 (or so) Radio Amateur's Handbook.? Their definition of UHF and the like has changed over the years.? They had

100 GHz is possible with coaxial cable. I doubt 1 THz is, but I don’t know. (Yes, I could use Google ???)

I think that microwaves is 10^-2 … 10^-3 meters free space wavelength range. Ing. Patricio A. Greco Taller Aeronáutico de Reparación 1B-349 Organización de Mantenimiento Aeronáutico de la

I think that in some cases it had to do with whether or not you had (or could) use waveguide.? Presumably if you could/had to do waveguide, that was a "microwave".? I think at one time it included

Many people consider microwaves to be above 1 GHz. That’s a sort of reasonable “definition”. I have never seen any authoritative document that defines where microwaves start and finish. >

They are not the same thing, but in the context of "radio frequency" the term radio is an adjective that just defines a certain range of frequencies, just as "audio frequency" defines a different

IMO, Pozar's book is more fundamental. Bowick like Pozar does seem to distinguish between RF design and microwave design... and between those and radio. IMO, they are not the same engineering

Roy, Have you read this? https://assets.cambridge.org/052183/5267/sample/0521835267ws.pdf You seem to be making comments about a book you've never read based on the title alone. Name someone making

Well that seems to be something that others are saying; Just the same, it is right to point out that while microwaves are not mutually exclusive to the term "radio" neither are they identical with it,

Given the rave reviews here of Tom Lee's book I've ordered a copy (and thanks for the clarifications). I'm now wondering if it's worthhwhile ordering the latest edition of Chris Bowick's 'RF Circuit

Thanks Wally, that protocol sounds good.? I see the mismatch curve is at much greater separations than I was thinking, with the smallest entry on the chart being 5 mils, which is close to the max

Neil, there are several versions of the Microwave Connector Care document but this HP 1986 version has the most N connector data on pages 45-52, see in particular figure 19 on page 48 for the effect

And make your own slotted line to measure frequency and other ancient gems. I worked as a research scientist/programmer. You can bluff people, but you can't bluff the computer. I knew many senior

Tom's book (ISBN 0521835267) is worth it just for the gems like how to cook your own point-contact copper-oxide detector diodes using a South Korean 10-won coin. I have a WW2 US Army high-impedance

A very basic aspect of books is reading them. If you don't or can't read them they are of no use. I have a 5000+ volume technical reference library. Many books were very expensive. Some I've read

I have an HP 905A sliding load which is complete with all of the interchangeable pins and bodies for male/female N and APC7, but there's a warning about never mating the connector pins with a
