On the use of the Padé-Fourier approximation in fast evaluation of the Green's function of layered media
Yakir Hadad
Efficient Green's function evaluation in layered media is a holy-grail of wave theory in general and for electromagnetics in particular. While there is a very large amount of knowl…
Beyond the Bode-Fano Bound: Wideband Impedance Matching for Short-Pulses using Temporal Switching of Transmission-Line Parameters
Amir Shlivinski, Yakir Hadad
Impedance matching is one of the most important practice in wave engineering as it enables to maximize the power transfer from the signal source to the load in the wave system. Unf…
Scattering theory from artificial piezoelectric-like meta-atoms and molecules
Leonid Goltcman, Yakir Hadad
Inspired by the natural piezoelectric effect, we introduce hybrid-wave electromechanical meta-atoms and meta-molecules that consist of coupled electrical and mechanical oscillators…
Clustering in particle chains - summation techniques for the periodic Green's function
Yarden Mazor, Yakir Hadad, Ben Z. Steinberg
1D lattice summations of the 3D Green's function are needed in many applications such as photonic crystals, antenna arrays, and so on. Such summations are usually divided into two…
Self-induced topological transitions and edge states supported by nonlinear staggered potentials
Yakir Hadad, Alexander B. Khanikaev, Andrea Alu
The canonical Su-Schrieffer-Heeger (SSH) model is one of the basic geometries that have spurred significant interest in topologically nontrivial bandgap modes with robust propertie…
Planar One-way Guiding in Periodic Particle Arrays with Asymmetric Unit Cell and General Group-Symmetry Considerations
Y. Mazor, Y. Hadad, Ben Z. Steinberg
We develop a general theory for one-way optical guiding in magnetized periodic particle arrays. Necessary conditions for a non-even dispersion curves are derived and presented in t…
Space-time gradient metasurfaces
Y. Hadad, D. L. Sounas, A. Alu
Metasurfaces characterized by a transverse gradient of local impedance have recently opened exciting directions for light manipulation at the nanoscale. Here we add a temporal grad…
One-way optical waveguides for perfectly matched non-reciprocal nano-antennas with dynamic beam tuning
Y. Hadad, Ben Z. Steinberg
An optical signal that propagates along a conventional waveguide is back reflected at waveguide terminations. If the waveguide permits only one-way propagation, this back reflectio…
Magnetized spiral chains of plasmonic ellipsoids for one-way optical waveguides
Y. Hadad, Ben Z. Steinberg
When a linear chain of plasmonic nano-particles is subject to longitudinal magnetic field, it exhibits optical Faraday rotation. If the magnetized nano-particles are plasmonic elli…
