Abstract
- The whispering-gallery (WG) mode 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--Complex source-point (CPS) beam, layered dielectric cylinder, Luneburg lens (LL), whispering-gallery (WG) modes.
