Abstract
The analysis of artificial perfectly magnetic conducting (PMC) surfaces is important, for the design of low-profile radiating structures. We studied the fields near the surface, with special attention given to evanescent waves present at small distances. A MoM-based code and a commercial software have been used to compute the fields scattered by an infinite and a finite PMC, respectively. It has been shown that the reactive fields are strong near the resonant frequency, with a particularly strong z circ component. They will certainly affect the antenna reactance. Truncation effects due to edge reflections are also stronger near the resonant PMC frequency.
