Microwave limiters implemented by coupled dielectric resonators based on a topological defect mode and CT-symmetry breaking
Mattis Reisner, Fabrice Mortessagne, Eleana Makri +2
We present a microwave realization of a reflective topological limiter based on an explicit self-induced violation of a charge-conjugation (CT) symmetry. The starting point is a bi…
Self-Shielded Topological Receiver Protectors
Mattis Reisner, Do Hyeok Jeon, Carsten Schindler +4
Receiver protectors (RPs) shield sensitive electronics from high-power incoming signals that might damage them. Typical RP schemes range from simple fusing and PIN diodes, to super…
Environmentally-induced exceptional points in elastodynamics
V. Dominguez-Rocha, Ramathasan Thevamaran, F. M. Ellis +1
We study the nature of an environment-induced exceptional point in a non-Hermitian pair of coupled mechanical oscillators. The mechanical oscillators are a pair of pillars carved o…
