Abstract
The spectral signatures of non-axially excited, absorbing TFHBM slabs are determined, after using a single-resonance Lorentzian model to describe the dispersive properties of the medium. Optical phenomena such as the optical rotation, circular dichroism and ellipticity transformation by absorbing TFHBM slabs are described. The effect of absorption on the functionality of TFHBM-based devices, such as multi-notch filters and ultranarrow-bandpass filters, are noted and engineering guidelines on the fabrication of such devices are provided.
