Recently, the quantum effect of condensed matter physics is introduced into the acoustic
field, which lays a new pathway to manipulate the acoustic wave. However, the acoustic …

We study the propagation of in-plane elastic waves in a soft thin strip, a specific geometrical

situations. Our focus lies on the quantum-optical dispersion interaction between a …

The space charge limit (SCL) of emission from photocathodes sets an upper limit on the
performance of both high-and low-field electron guns. Generally, one is forced to strike a …
