Enhanced Signal-to-Noise Performance of EP-based Electromechanical Accelerometers
Rodion Kononchuk, Jizhe Cai, Fred Ellis +2
Exceptional points (EP) are non-Hermitian spectral degeneracies where both eigenvalues and their corresponding eigenvectors coalesce. Recently, EPs have attracted a lot of attentio…

Orientation-sensed Optomechanical Accelerometers based on Exceptional Points
Rodion Kononchuk, Tsampikos Kottos
We propose an optomechanical design, consisting of a parity-time symmetric multilayer structure tuned at exceptional-point degeneracy (EPD), with an adjustable layer that is couple…

Free-Space Wide-Aperture Sheet-Isolator Based on a Multilayered Resonant Cavity
R. Kononchuk, C. Pfeiffer, I. Anisimov +3
We introduce the first conceptual design of a free-space thin-sheet isolator with unlimited aperture and the possibility of a broadband omnidirectional rejection of the backward pr…
