A fission transmission linear-to-circular polarization conversion based on bi-layer structure is proposed which is composed of 3 × 3 array to convert linear-to-circular polarized wave. The structure is constructed by half square with “H” shape printed on both sides of the dielectric substrate that are subjected to obtain multi-band at resonance frequencies. The proposed structure realizes the giant circular polarization under the normal incidence for right and left circular polarized waves. After transmission, the incident wave decomposed into two orthogonal linear components have equal magnitudes and 90o phase difference between them. The novel approach of “fission transmission of electromagnetic waves” is firstly introduced to understand the physics of giant circular polarization conversion which is based on the sequence of incident and transmitted waves to generate strong circular dichroism.
