Description
Experimental validation of the thermoelastic expansion hypothesis in the microwave auditory effect is crucial. The objective of this study was to induce and measure thermoelastic waves generated on a dielectric phantom simulating the human head when exposed to microwave pulses. The measurement utilized a Laser Doppler Vibrometer based on heterodyne interferometry. The experiment, conducted with 2450 MHz microwave pulses under controlled Pulse Width (PW) [µs], Pulse Repetition Frequency (PRF) [Hz], and Power [kW] conditions, successfully captured the induced thermoelastic waves within a 3 MHz bandwidth.
