Abstract

The waveguiding properties of sculptured nematic thin films (SNTFs) are investigated. A theoretical framework to determine the modal wavenumbers and modeshapes for guided wave propagation through these anisotropic microcolumnar mediums is presented. Numerical results are provided to illustrate the characteristics of guided wave propagation through C-SNTFs. The differences between guided wave propagation in such mediums and the corresponding isotropic thin films are highlighted.
