Infinitely thin planar circuits are often represented with rooftop basis functions. These basis functions use a sheet of surface current over the area of a subsection and are overlapped to generate a piece-wise linear representation of the actual sur

Roger Harrington had major influence in many areas of electromagnetics with his formalization of the method of moments. This paper describes his influence in the early application of the method of moments to analysis of shielded planar microwave circ

Should you wish to pay homage to the great physicist James Clerk Maxwell, you wouldn’t lack for locales in which to do it. There’s a memorial marker in London’s Westminster Abbey, not far from Isaac Newton’s grave. A magnificent statue was re

Port tuning is a form of space mapping that allows rapid optimization of filters and other microwave circuits. An initial electromagnetic (EM) analysis of the filter with tuning ports inserted in all resonators is performed. Then small circuit theory
