Trapped-mode resonances in optical planar metamaterials with metal elements

Paper deals with analysis of the ldquotrapped moderdquo resonance properties in optical planar structures for metamaterials applications. The light diffraction solve algorithm for planar periodic metal-dielectric optical structures combines the mapped PSTD method with analytical transfer matrix method. The wavelength dependencies of reflection coefficients for periodic array with broken c-shaped and circle metal elements are presented.
