Indeed, and I think I have most of them in my library. Today, I had the foresight to grab both volumes of "Antenna Theory" from my office at work. Parasitic arrays are discussed in Volume 1, pp

In a PM Kai mentioned "EM slow wave structures", something I'd never heard of. I started this as a reply to him, but decided it might be of more general interest to the list. A perusal of 2 ft of

Collin was a somewhat prolific writer of text books about EM fields, propagation and antennas. I think he was the author or co-author of six or seven different books. DaveD

An excellent history of the above is contained in Bruce R. Hunt’s “The Maxwellians”, which, IIRC, includes a comparison of Maxwell’s original equations and Heaviside’s final forms using

Do *not* underestimate the power of "operational mathematics". Oliver Heaviside was correctly solving problems that the mathematicians couldn't solve for years before some of them were intrepid

For Collin & Zucker. Lawson is between $20 and $90-something. from sone sketchy booksellers.

Bookfinder was vol 1& 2 for $485

On that note, another book by Collin ("Antennas and Radiowave Propagation) that isn't in my work office has this to say about parasitic arrays: I certainly don't think discussing the possibility of

bookfinder. com finds sone copies of Lawson. Somewhat expensive second-hand (but not $500!). DaveD

Might be worth trying on a Pi 4. It is _much_ more powerful than any previous Pi. Sean

Out of print books, ugh. Reminds me of a class I took where the instructor wanted to use Christopher Van Wyk's excellent "Data Structures and C Programming" which is out of print. Van Wyk was

gcc is a free compiler, that compiles Fortran, as well as numerous other languages. Octave is a free clone of MATLAB, but it does not have the extensive range of toolboxes support that MATLAB has, so

I see one copy available. $485. Wow. I bought my set used in the early 80s when I was collecting all of Collin’s work. I think I paid around $100 for the set. DaveD

Thank you, Sean. Yes, that is a very good set of texts about antennas. I haven’t looked in a while, but I believe it is now completely unavailable. Krieger or someone (is Dover still around?)

Ouch!!!!! $500 and up used!

Indeed...I couldn't think of the co-author's name to save my life either! Sean
