Radiation patterns of sources placed near the truncation of a semi-infinite dielectric structure: the demonstration case of a magnetic line current

Numerical methods are presented to estimate the radiation pattern of a magnetic line current placed near the truncation of a dielectric structure. The problem is solved using the integral equation technique, expansion wave concept, and physical optics approximation. The comparison between different...

Beschreibung
Zusammenfassung:	Numerical methods are presented to estimate the radiation pattern of a magnetic line current placed near the truncation of a dielectric structure. The problem is solved using the integral equation technique, expansion wave concept, and physical optics approximation. The comparison between different methods permits to understand better the possibilities of each of the methods.
