Oral/2009: Wave Propagation Method as an Accurate Technique for Effective Refractive Index Retrieving
Andrei Andryieuski1, Radu Malureanu1, Andrei Lavrinenko1
1DTU Fotonik – Department of Photonics Engineering, Technical University of Denmark, Build. 343, DK-2800, Kgs. Lyngby, Denmark
Abstract: An effective parameters retrieval method based on the wave propagation simulation is proposed and compared with the standard S-parameter procedure. The method is free from...
Oral/2010: Is It Possible To Homogenize Resonant Chiral Metamaterials?
Andrei Andryieuski1, Christoph Menzel2, Carsten Rockstuhl2, Radu Malureanu1, Falk Lederer2, Andrei Lavrinenko1
