DOI: 10.1016/j.ijleo.2018.04.009

Abstract: Abstract Modified theory of physical optics (MTPO) solution for a soft/hard strip is analyzed. It is shown that this solution is incorrect because the MTPO Green function does not satisfy boundary conditions. Defects of MTPO… read more here.

DOI: 10.1109/lawp.2017.2675443

Abstract: A fast shadowing algorithm based on Levin method is proposed for physical optics (PO) integrals from the targets modeled with a B-spline surface. The CPU time of the proposed algorithm is independent of incident frequency.… read more here.

DOI: 10.1109/tap.2019.2894320

Abstract: Time-domain physical optics (TDPO) contour integral representations are developed for backscattered near fields from a perfectly conducting surface illuminated by a dipole source. The proposed representations are derived from the TDPO surface integral representations by… read more here.

DOI: 10.1364/oe.396577

Abstract: Phasor-field (P-field) imaging is a promising recent solution to the task of non-line-of-sight (NLoS) imaging, colloquially referred to as "seeing around corners." It consists of treating the oscillating envelope of amplitude-modulated, spatially-incoherent light as if… read more here.
