Giant Rotational Meta-Doppler from Genetically Designed Superscatterers
Dmytro Vovchuk, Sergey Geyman, Konstantin Grotov +10
The motion of a rigid body interacting with a wave leaves spectral signatures, with the Doppler shift as the dominant contribution. Since any motion can be decomposed into translat…
Gradient-based optimization of scatterer arrangements based on the T-matrix method
Nigar Asadova, Jan David Fischbach, Renaud Vallée +6
The demand for inverse design is increasing as the ability to fabricate sub-10 nm features expands the design space by orders of magnitude. Efficient inverse design benefits from d…

O. Yerushalimov, D. Vovchuk, A. Glam +1
The rapid deployment of drones poses significant challenges for airspace management, security, and surveillance. Current detection and classification technologies, including camera…
Optically Transparent Meta-Grating Embedded in Rear Windshields for Automotive Radar Detection
Sergey Geyman, Dmytro Vovchuk, Denis Kolchanov +9
Radar plays a crucial role in automotive safety by enabling reliable object detection, thereby assisting drivers and, prospectively, serving as one of the primary sensors in autono…
Drone Carry-on Weight and Wind Flow Assessment via Micro-Doppler Analysis
Dmytro Vovchuk, Oleg Torgovitsky, Mykola Khobzei +11
Remote monitoring of drones has become a global objective due to emerging applications in national security and managing aerial delivery traffic. Despite their relatively small siz…
3D Genetic Metamaterials for Scattering Maximization
Dmitry Dobrykh, Anna Mikhailovskaya, Konstantin Grotov +6
The rapidly growing volume of drone air traffic demands improved radar surveillance systems and increased detection reliability in challenging conditions. The scattering cross-sect…
