Exactly Solvable Diffraction-Grating Scattering Problems for TE and TM waves
Farhang Loran, Ali Mostafazadeh
The paper extends Berry's analytically solvable diffraction-grating model to a broader class of possibly magnetic gratings and provides exact solutions for both transverse electric…
Scattering of TE and TM waves by inhomogeneities of a 2D material, low-frequency behavior of the scattering amplitude, and low-frequency invisibility
Farhang Loran, Ali Mostafazadeh
The propagation of the transverse electric (TE) and transverse magnetic (TM) waves in an effectively two-dimensional (2D) isotropic medium is described by Bergmann's equation of ac…
Does a Curved Mirror Honestly Reflect Your Identity? A Study of Multipole Images in Front of a Grounded Sphere
Farhang Loran, Saman Moghimi-Araghi
The method of image charges is a powerful and elegant technique in electrostatics, commonly used to determine the electric field generated by point charges near conductors of vario…
Reciprocity Theorem and Fundamental Transfer Matrix
Farhang Loran, Ali Mostafazadeh
Stationary potential scattering admits a formulation in terms of the quantum dynamics generated by a non-Hermitian effective Hamiltonian. We use this formulation to give a proof of…
Low-Frequency Scattering of TE and TM Waves by an Inhomogeneous Medium with Planar Symmetry
Farhang Loran, Ali Mostafazadeh, Cem YetiÅmiÅoÄlu
Stationary scattering of TE and TM waves propagating in an isotropic medium with planar symmetry is described by Bergmann's equation in one dimension. This is a generalization of H…
Dynamical formulation of low-frequency scattering in two and three dimensions
Farhang Loran, Ali Mostafazadeh
The transfer matrix of scattering theory in one dimension can be expressed in terms of the time-evolution operator for an effective non-unitary quantum system. In particular, it ad…
