Time-Varying Wireless Power Transfer Systems for Improving Efficiency
X. Wang, I. Krois, N. Ha-Van +4
Conventional wireless power transfer systems are linear and time-invariant, which sets fundamental limitations on their performance, including a tradeoff between transfer efficienc…
Molding of Reflection and Scattering from Uniform Walls Using Space-Periodic Metasurfaces
S. Kosulnikov, F. S. Cuesta, X. Wang +1
Active development is taking place in reconfigurable and static metasurfaces that control and optimize reflections. However, existing designs typically only optimize reflections fr…
Antenna bandwidth engineering through time-varying resistance
M. H. Mostafa, N. Ha-Van, P. Jayathurathnage +3
Operational bandwidth of resonant circuits is limited by the resonator's size, which is known as the Chu limit. This limit restricts miniaturization of antennas, as the antenna ban…
Coherent Asymmetric Absorbers
F. S. Cuesta, A. D. Kuznetsov, G. A. Ptitcyn +2
Most applications of metasurfaces require excitation and control of both electric and magnetic surface currents. For such purpose, the metasurface must have a finite thickness to h…
