Optical diodes controlling the flow of light are of principal significance for optical information
processing. They transmit light from an input to an output, but not in the reverse direction …

Nonreciprocal devices that allow unidirectional wave propagation are indispensable in
many scientific fields, including, for example, optics, acoustics, electronics, and …

A mechanism for asymmetric (nonreciprocal) wave transmission is presented. As a
reference system, we consider a layered nonlinear, nonmirror-symmetric model described …

We theoretically investigate the quantum coherence and its nonreciprocity in a cavity
magnomechanical system composed of a spinning microwave resonant cavity and an …

In the present paper, we consider nonlinear PT-symmetric dimers and trimers (more
generally, oligomers) embedded within a linear Schrödinger lattice. We examine the …

We study scattering of a periodic wave in a string on two lumped oscillators attached to it.
The equations can be represented as a driven (by the incident wave) dissipative (due to …

How to control electromagnetic wave effectively is the key to the realization of applicable
filters in many optics technologies. In our work, a SU-8 photoresist micro-disk is written onto …

计算了厚度调制的双周期一维光子晶体的能带. 当一维光子晶体的厚度被周期性地调制时,
原来的能带分裂为许多子能带, 其中一些很窄的子能带进入了原来的单周期光子晶体的带隙内 …

Unidirectional nonreciprocal transport is at the heart of many fundamental problems and
applications in both science and technology. Here we study the novel design of wave diode …

In this work, we theoretically investigate the propagation of terahertz (THz) waves through a
graphene-loaded metal grating under external magnetic field. It is found that resonant …
