Scattering Matrix Method

Localized and resonant state energies of coulomb acceptor in narrow-gap HgCdTe alloy are calculated at different temperatures. A universal technique for estimation of localized and resonant state energies is suggested. It is shown theoretically that these energies are туфкдн constant in a wide range of temperatures from 0 to 100 K. The simulation is performed with scattering matrix method within spherically-symmetric three-band Kane model that takes into account the conduction band two valence bands.

Abstract The energies and wavefunctions of both localized and resonant states are calculated for Coulomb acceptor in narrow-gap HgCdTe alloys with cadmium mole fraction from 0 to 30%. The simulation is performed with scattering matrix method within a spherically-symmetric three-band Kane model that takes into account the conduction band and two valence bands. The energies of both localized and resonant states are determined using the localization rate magnitude, introduced in this work.

Novel Design

The design of spatially varying lens antennas based on artificial materials is of high interest for their wide range of applicability. In this paper, we propose a novel design procedure relying on an inverse formulation of the scattering matrix method (SMM). Differently from many adopted approaches, which resort to global optimizations or homogenization procedures, the inverse SMM (I-SMM) allows the synthesis of optimal parameters (geometrical and/or electromagnetic) for the inclusions realizing the overall device in a very effective manner. With reference to the 2D TM case, the proposed tool has been successfully assessed through the synthesis of different kinds of lenses radiating a pencil beam.
