Optical Limiter Based on PT-Symmetry Breaking of Reflectionless Modes
F. Riboli, R. Kononchuk, F. Tommasi +8
The application of parity-time (PT) symmetry in optics, especially PT-symmetry breaking, has attracted considerable attention as a novel approach to controlling light propagation.…
Towards a Broad-Band Coherent Perfect Absorption in systems without Scale-Invariance
Suwun Suwunnarat, Yaqian Tang, Mattis Reisner +3
We experimentally and theoretically challenge the concept of coherent perfect absorption (CPA) as a narrow frequency resonant mechanism associated with scattering processes that re…
A reflective mm-wave photonic limiter
Rodion Kononchuk, Suwun Suwunnarat, Martin S. Hilario +6
Millimeter wave (mm-wave) communications and radar receivers capable of processing small signals must be protected from high-power signals, which can damage sensitive receiver comp…
Floquet Perfect Absorbers based on Periodically Driven Targets
Dashiell Halpern, Suwun Suwunnarat, Huanan Li +2
We introduce the concept of multichannel Floquet Perfect Absorbers (FPAs) which are periodically modulated lossy interferometric traps that completely absorb incident monochromatic…
Statistical Design of Chaotic Waveforms with Enhanced Targeting Capabilities
Huanan Li, Suwun Suwunnarat, Tsampikos Kottos
We develop a statistical theory of waveform shaping of incident waves that aim to efficiently deliver energy at weakly lossy targets which are embedded inside chaotic enclosures. O…
Random Matrix Theory Approach to Chaotic Coherent Perfect Absorbers
Huanan Li, Suwun Suwunnarat, Ragnar Fleischmann +2
We employ Random Matrix Theory in order to investigate coherent perfect absorption (CPA) in lossy systems with complex internal dynamics. The loss strength and energy…
Distribution of zeros of the S-matrix of chaotic cavities with localized losses and Coherent Perfect Absorption: non-perturbative results
Yan V. Fyodorov, Suwun Suwunarat, Tsampikos Kottos
We employ the Random Matrix Theory framework to calculate the density of zeroes of an -channel scattering matrix describing a chaotic cavity with a single localized absorber emb…
Low-Temperature Linear Thermal Rectifiers Based on Coriolis forces
Suwun Suwunnarat, Huanan Li, Ragnar Fleischmann +1
We demonstrate that a three-terminal harmonic symmetric chain in the presence of a Coriolis force, produced by a rotating platform which is used to place the chain, can produce the…
