Acoustic Metamaterials

I wroked on specific type of metamaterials to process sonic waves using geometrical cavities. The aim is to develope basic signal processing operations like Fast Fourier Transform (FFT), Low Pass Filter, High Pass Filter etc using geometry. Apart from the end user applications, the construction, mechanisms and underlying principles for such metamaterials are also interesting from the fundamental physics point of view. It was the major part of the work I did for my Master's Thesis at IIT Roorkee in collaboration with the HCI Group at Saarland University, Germany.
