Design and Analysis of Disordered Optical Nanoantenna Structures

摘要: Nanoantennas are optical wave radiating structures operating based on the same physical principles as those underlying their radio-frequency counterparts. However, properties of materials in range frequency cause different response to incident electromagnetic field leading novel applications optics. The conventional methods for analysis and design antennas need be modified these structures. In this paper, an integral equation formulation using complex images Green's function technique is employed model interactions with nanoantennas embedded multilayer media. developed method combined simulated annealing algorithm optimize composed strongly coupled nanoscale scatterers. It shown that not only can they lead improved efficiency devices, but also orthogonal transmission channels attainable when excited properly. latter provides a new scheme encoding multiplexing signals information systems.
