The multiplexing principle originates from the phase-matching requirement for coupling between the waveguide mode and free space. For the lowest-order transverse-electric (TE 1) mode of a PPWG, the ...
Recent advances in the study of acoustic radiation and vibrational analysis of circular plates have significantly deepened our understanding of how structural motions generate sound. This field ...
Parallel plates: illustration of the quartz plates used to measure heat transfer. (Courtesy: M Ghashami et al/Phys. Rev. Lett.) New insights into why heat transfer between objects is enhanced at very ...
