波束馈电圆形分层介质柱中的回音壁和Luneburg透镜效应

Whispering-gallery and Luneburg-lens effects in a beam-fed circularly-layered dielectric cylinder

A. V. Boriskin, A. I. Nosich

摘要:

研究了有耗圆形分层介质柱在光束场作用下的回音壁模激发和Luneburg透镜效应。后者是由复杂的源点(CSP)光束模拟。波散射问题的精确级数解用于获得远场方向图和方向性。WG模式的效果被证明是破坏LL性能。索引条款:分层圆形介质柱,复源点波束,回音壁模式,Luneburg透镜。

英文摘要:

The whispering-gallery mode (WGM) excitation and Luneburg lens (LL) effect are studied for a lossy circularly-layered dielectric cylinder illuminated by a beam field. The latter is simulated by the Complex Source-Point (CSP) beam. Exact series solution to the wave scattering problem is used to obtain the far-field patterns and directivity. The WG mode effect is shown to undermine the LL performance. Index Terms: Layered circular dielectric cylinder, Complex source point beam, Whispering-gallery modes, Luneburg lens.
