DOI: 10.1016/j.commatsci.2018.10.016

Abstract: Abstract We present Trotter-Suzuki-time propagation method to calculate the Density of States (DOS) of disordered (i.e., vacancy and hydrogen adatom impurities) graphene system for the size of up to ≈16,000,000 atoms. The method is based… read more here.

DOI: 10.1109/jphot.2020.3029032

Abstract: This paper presents structural optimization based on sensitivity analysis exploiting a bi-directional beam propagation method (Bi-BPM) to design efficiently passive components in high-index-contrast optical waveguides. In this study, the Bi-BPM based on scaled-version Denman-Beavers iteration… read more here.

DOI: 10.1364/ol.44.004989

Abstract: Scattering is one of the main issues that limit the imaging depth in deep tissue optical imaging. To characterize the role of scattering, we have developed a forward model based on the beam propagation method… read more here.
