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.
