Concealing objects from interrogation has been a primary objective since the integration of
radars into surveillance systems. Metamaterial-based invisibility cloaking, which was …

Motion signatures of nonstationary electromagnetic bodies are imprinted in their scattering
spectrum. While the Doppler frequency shift holds information about the velocity of its center …

While software-defined radars can switch their transmitted waveform on the go, they cannot
transmit all waveforms at the same time, meaning they must balance the advantages and …

Interaction of electromagnetic, acoustic, and even gravitational waves with accelerating
bodies forms a class of nonstationary time-variant processes. Scattered waves contain …

Metamaterials are artificially created media, which allow introducing additional degrees of
freedom into electromagnetic design by controlling constitutive material parameters …

A cloaking and/or deception system comprises: a structure having a plurality of resonators
characterized by a controllable resonance frequency, wherein the resonators are arranged …
