The optimal parameters of a dielectric metasurface, composed of two alternating rectangular rods, are investigated so that it exhibits significant enhancement in the −1- diffracted order in the transmission region. An ...

A ground-penetrating radar (GPR) antenna excites a perfectly electric conducting inclusion buried inside the ground. The scattering problem is solved semi-analytically via integral equation techniques. The permittivity and ...

The speed with which electromagnetic energy can be wirelessly transferred from a source to the user is a crucial indicator for the performance of a large number of electronic and photonic devices. We expect that ...

Giant in-plane anisotropy can be exhibited by a finitely thick periodic multilayer comprising bilayers of an isotropic noncentrosymmetric material and a non-dissipative isotropic medium of negative permittivity, when a ...

Gratings of infinite wires make, perhaps, the simplest class of metasurfaces, which, however, are utilized for a variety of different objectives in wave manipulation. Importantly, due to their analytical solvability, ...

We show and investigate the optical forces acting on a particle in the vicinity of a planar waveguide which is lled with hyperbolic material and supports propagation across its plane (two-dimensional). The anisotropy ...

Wave polarization contains valuable information for electromagnetic signal processing; thus, the ability to manipulate it, can be extremely useful in modeling photonic devices. In this work, we propose designs comprised ...

We show how by a tailored breaking of the translational symmetry in waveguides and optical bers one can control chromatic dispersions of the individual modes at any order and thereby overcome the problem of coherent ...

How one can fabricate the Parity-Time (PT) symmetric siblings of commonly used metals in the visible? This work tries to give an answer to that question by providing the features of the active media which conjugately ...

Lens design for focusing and imaging has been optimized through centuries of developments; however, conventional lenses, even in their most ideal realizations, still suffer from fundamental limitations, such as limits ...
