The bulk-boundary correspondence and Chern number are well-known features of non-trivial topological systems. Here, the authors confirm the bulk-edge correspondence by observing pumping in a one-dimensional topological electric circuit emulating a Ch

A magnetically coupled three-coil system to have one transmitting and two receiving coils is considered. We show that the position of the transmitting coil can be estimated from the ratio of received wave amplitudes and its angular derivative when th

Vanadium dioxide (VO2) is a promising phase-change material (PCM) in controlling radiative heat transfer because of the large permittivity contrast between the phases and the moderate metal-insulator transition temperature of 340 K. Widely adopted ba

In this paper, a novel graphene-based multiple-input multiple-output (MIMO) concept is proposed for high-rate nanoscale wireless communications between transceivers, which are nano/micrometers apart from each other. In particular, the proposed MIMO a

We investigate acoustic wave coupling between two resonators of very different intrinsic losses, e.g. lossy and lossless resonators as an extreme case. We find that the resonator pair placed on a reflector exhibits angle-dependent absorption, showing

Memristor provides nonlinear response in the current-voltage characteristic and the memristance is modulated using an external voltage source. We point out by solving nonlinear equations that an optimal condition of the external voltage source exists
