Novel Simulation Of Ultrasonic Attenuation In Fourier Transform Analog Computing

Ultrasonic Fourier Transform analog computing uses acoustic waves propagating across fused silica and an acoustic lens to compute the Fourier Transform. We demonstrate a method to incorporate not only the attenuation of ultrasonic waves in the fused silica medium, but also the transmittance of the a...

Summary:Ultrasonic Fourier Transform analog computing uses acoustic waves propagating across fused silica and an acoustic lens to compute the Fourier Transform. We demonstrate a method to incorporate not only the attenuation of ultrasonic waves in the fused silica medium, but also the transmittance of the acoustic meta-lens into our 3D hybrid simulation integrating both finite element analysis and Fresnel diffraction. Our realistic simulation predicts the effect of acoustic attenuation on the voltage at the receiver pixel array, which guides electrical specifications for the low-noise amplifier at the RX CMOS circuit, to maximize the readout signal-to-noise ratio.
