Question
the literature source [POZAR] is available here:
https://www.amazon.co.uk/Microwave-Engineering-David-M-Pozar/dp/0470631554
There's also a solutions manual available here:
https://www.scribd.com/doc/176505749/Microwave-engineering-pozar-4th-Ed-solutions-manual
Answer
In this example, the 1st attached pack pozar_05_Example_02.zip uses intersections.m while the 2nd attached pack pozar_05_example_02_2.zip uses the simplified circles_intersect.m instead.
A 3rd attachment to just test this alternative support function circles_intersect.m
