Shadow-Free Scattering with Complex Frequency Excitations
Vitali Kozlov, Wei Wang, Seunghwi Kim +2
The optical theorem dictates that the wave scattering of an object in the forward direction is proportional to the total power extinguished from the excitation. For passive objects…
Radar Range Deception with Time-Modulated Scatterers
V. Kozlov, D. Vovchuk, P. Ginzburg
Modern radar systems are designed to have high Doppler tolerance to detect fast-moving targets. This means range and Doppler estimations are inevitably coupled, opening pathways to…
Partially Coherent Radar Unties Range Resolution from Bandwidth Limitations
Rony Komissarov, Vitali Kozlov, Dmitry Filonov +1
It is widely believed that range resolution, the ability to distinguish between two closely situated targets, depends inversely on the bandwidth of the transmitted radar signal. He…
Memory Effects in Scattering from Accelerating Bodies
V. Kozlov, S. Kosulnikov, D. Vovchuk +1
Interaction of electromagnetic, acoustic and even gravitational waves with accelerating bodies forms a class of nonstationary time-variant processes. Scattered waves contain intrin…
Coupled Micro-Doppler Signatures of Closely Located Targets
Vitali Kozlov, Sergey Kosulnikov, Dmitry. Filonov +2
The classical Doppler shift originates from the movement of a target's center of mass, but it does not hold information about the internal dynamics of the scattering object. In con…
Broadband Radar Invisibility with Time-Dependent Metasurfaces
Vitali Kozlov, Dmytro Vovchuk, Pavel Ginzburg
Concealing objects from interrogation has been a primary objective since the integration of radars into surveillance systems. Metamaterial-based invisibility cloaking, which was co…
Asymmetric Backscattering from the Hybrid Magneto-Electric Meta Particle
Vitali Kozlov, Dmitry Filonov, Alexander S. Shalin +2
The optical theorem relates the total scattering cross-section of a given structure with its forward scattering, but does not impose any restrictions on other directions. Strong ba…
Resonant Meta-atoms with Nonlinearities on Demand
Dmitry Filonov, Yotam Kramer, Vitali Kozlov +2
Nonlinear light-matter interactions and their applications are constrained by properties of available materials. The use of metamaterials opens the way to achieve precise control o…
Micro-Doppler Frequency Comb Generation by Axially Rotating Scatterers
Vitali Kozlov, Dmitrii Filonov, Yefim Yankelevich +1
Electromagnetic scattering in accelerating reference frames inspires a variety of phenomena, requiring employment of general relativity for their description. While the quasi-stati…
