I need a good reference for multiport junction in microwave system. For example, how to connect a load between two different ports of a multiport system.
I guess this book (D. M. Sazonov, "Antennas and Microwave Circuits", 1988) could have a lot helpful information. But the problem is that text book is out of print and it is currently too expensive to purchase: https://www.amazon.com/Microwave-Circuits-Antennas-D-Sazonov/dp/503001411X
