Abstract

The investigation of the far-field radiation from a dipole source inside an infiltrated chiral sculptured thin films (CSTF) was extended to consider different positions of the dipole source and the presence or absence of fluid above the CSTF. From numerical studies, we found that within one structural period, the far-field radiation pattern varies as the source position varies and the pattern approximately repeats when the source is moved by one structural period. The intensity of the emitted radiation is less influenced by the presence of fluid above the CSTF. When the source is placed at the centre of the CSTF, the right circular polarization radiation is preferentially emitted through upper face of the CSTF whereas left circular polarization radiation is preferentially emitted through lower face.
