Introducing a general method for solving electromagnetic radiation problem in an arbitrary linear medium
Farhang Loran, Ali Mostafazadeh
Numerical transfer matrices have been widely used in the study of wave propagation and scattering. These may be viewed as descretizations of a recently introduced fundamental notio…
Broadband directional invisibility
Farhang Loran, Ali Mostafazadeh
The discovery of unidirectional invisibility and its broadband realization in optical media satisfying spatial Kramers-Kronig relations are important landmarks of non-Hermitian pho…
Low-frequency scattering defined by the Helmholtz equation in one dimension
Farhang Loran, Ali Mostafazadeh
The Helmholtz equation in one dimension, which describes the propagation of electromagnetic waves in effectively one-dimensional systems, is equivalent to the time-independent Schr…
Active Invisibility Cloaks in One Dimension
Ali Mostafazadeh
We outline a general method of constructing finite-range cloaking potentials which render a given finite-range real or complex potential unidirectionally reflectionless or i…
