Tutorial on basics of time-varying electromagnetic systems and circuits
G. Ptitcyn, M. S. Mirmoosa, A. Sotoodehfar +1
During the last decade, possibilities to realize new phenomena and create new applications by varying system properties in time have gained increasing attention in many research fi…
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…
Loss-induced performance limits of all-dielectric metasurfaces for terahertz sensing
J. A. Álvarez-Sanchis, B. Vidal, S. A. Tretyakov +1
Metasurfaces providing resonances arising from quasi-bound states in the continuum have been proposed as sensors in the THz band due to the existence of strong resonances character…
Emulating Bianisotropic Coupling Through Coherent Illumination
F. S Cuesta, M. S. Mirmoosa, S. A. Tretyakov
One of the main advantages of reciprocal bianisotropic metasurfaces is their capability to produce asymmetric scattering depending from which side they are illuminated and on the h…
Multi-functional metasurface architecture for amplitude, polarization and wavefront control
A. Pitilakis, M. Seckel, A. C. Tasolamprou +10
Metasurfaces (MSs) have been utilized to manipulate different properties of electromagnetic waves. By combining local control over the wave amplitude, phase, and polarization into…
Parametric Mie resonances and directional amplification in time-modulated scatterers
V. Asadchy, A. G. Lamprianidis, G. Ptitcyn +7
We provide a theoretical description of light scattering by a spherical particle whose permittivity is modulated in time at twice the frequency of the incident light. Such a partic…
