Maximum Willis Coupling in Acoustic Scatterers
Li Quan, Younes Ra'di, Dimitrios Sounas +1
Willis coupling in acoustic materials defines the cross-coupling between strain and velocity, analogous to bianisotropic phenomena in electromagnetics. While these effects have bee…
Meta-Gratings: Beyond the Limits of Graded Metasurfaces for Wavefront Control
Younes Ra'di, Dimitrios L. Sounas, Andrea Alu
Graded metasurfaces exploit the local momentum imparted by an impedance gradient to transform the impinging wavefront. This approach suffers from fundamental limits on the overall…
On-Site Wireless Power Generation
Y. Ra'di, B. Chowkwale, C. A. Valagiannopoulos +4
Conventional wireless power transfer systems consist of a microwave power generator and a microwave power receiver separated by some distance. To realize efficient power transfer,…
Self-Oscillating Wireless Power Transfer Systems
Sergei A. Tretyakov, Constantin R. Simovski, Constantinos A. Valagiannopoulos +1
Conventional wireless power transfer systems consist of a microwave power generator and transmitter located at one place and a microwave power receiver located at a distance. Here…
Optimization of optical absorption in thin layers of amorphous silicon enhanced by silver nanospheres
Mikhail Omelyanovich, Younes Ra'di, Constantin Simovski
We study a highly controllable perfect plasmonic absorber -- a thin metamaterial layer which possess balanced electric and magnetic responses in some frequency range. We show that…
Polarizabilities of nonreciprocal bianisotropic particles
M. S. Mirmoosa, Y. Ra'di, V. S. Asadchy +2
For two electrically small nonreciprocal scatterers an analytical electromagnetic model of polarizabilities is developed. Both particles are bianisotropic: the so-called Tellegen-o…
