Query: Hyperbolic Metamaterial Filter for Angle-independent TM-Transmission in
  Imaging Applications   With conventional narrowband filters, the center-wavelength of the narrow
transmission band undergoes large shifts as the angle of incident light
changes. In this project, we designed and experimentally verified a type of
hyperbolic metamaterial Bragg stack that eliminates, or vastly reduces, this
angle-of-incidence dependence (i.e., dispersion) of the transmission band for
TM polarized beam. The filter developed in this project is composed of array of
subwavelength sized metal wires vertically penetrating in the dielectric layers
of the Bragg stack. We first discuss the physical reasons why such a structure
is expected to minimize dispersion, then we performed detailed electromagnetic
modeling, fabrication of proof-of-concept structures, and optical testing of
the structures. The filter is fabricated by CMOS fabrication techniques and
optical characterized using Fourier-transform infrared spectroscopy. Both
simulated and experimental data show that narrow band transmission filters can
be designed such that the center-wavelength of the transmission peak for TM
polarized incident light does not change as the angle of incidence of an
incoming beam changes. These types of narrowband notch filters have been used
in many sensing and imaging applications, including remote sensing and
hyperspectral imaging.
