Modulation schemes for the audio beam system : fixed-point analysis, simulation and implementation by Seth, Abhishek

“…Directional sound can be created by modulating an audible signal onto an ultrasonic carrier and projecting the modulated signal via special types of ultrasonic transducer to generate the parametric array through air, in such a way that audible sound can travel in a column of sound beams. The device that generates this phenomenon is generally referred to as the parametric loudspeaker. …”

Plasmon excitation on flat graphene by s-polarized beams using four-wave mixing by Tao, Jin, Dong, Zhaogang, Yang, Joel K. W., Wang, Qi Jie

“…However, exciting plasmons on graphene effectively still remains a challenge owing to the large wave-vector mismatch between the optical beam in air and graphene plasmon. In this paper, we present a novel scheme capable of exciting graphene surface plasmons (GSPs) on a flat suspended graphene by using only s-polarized optical beams through four-wave mixing (FWM) process, where the GSPs fields were derived analytically based on the Green's function analysis, under the basis of momentum conservation. …”
