Radiation pressure of a hybrid bianisotropic chiral structure

Abstract

Abstract To obtain radiation pressure of a hybrid chiral structure, we derive the transfer matrix method and optical force densities from the Maxwell stress tensor for a planar layered bianisotropic media. The key derivations are how to get wavevectors and field components of each layer, transfer matrices connecting four eigenwaves of adjacent chiral media, as well as the force densities expressed by co- and cross-polarized reflection and transmission coefficients. After the validation of the methods and programs is performed, the radiation pressure of a layered biaxial bianisotropic chiral slab is studied. The effects of linearly and circularly polarization incident waves, incident angle, thickness, opposite handedness (optical activity), anisotropy, gain and loss of chiral media on the radiation pressure are discussed. Our work elucidates the mechanism of light-chiral media interactions, provides better understanding of chiral detection, optical trapping, and biophysics.
