Paper Abstract

Numerical, theoretical and experimental results on the use of combinations of surface plasmons, waveguide and diffraction modes to control the flow of light in transmission gratings, are described. Methods of designing compound gratings that have multiple, differently composed grooves within each period and that selectively transmit, at anomalously large amounts, s-polarized or p-polarized light, are described. It is shown how the ability to separate the polarization components and have them transmitted into different portions of the substrate can be used to design polarimetric sensors. Related phenomena of light circulation and weaving due to the excitation of phase resonances are described.
