Designing of acoustic Half Adder and Half Subtractor using fluid–fluid phononic crystal based ring resonator

This work presents a novel design that uses a fluid–fluid 2D phononic crystal ring resonator (PnC-RR) as a half adder and half subtractor. Based on acoustic waveguides and a crystal ring resonators cavity operating at a single frequency of 45.1 kHz, the suggested Half Adder/Half Subtractor construction is presented. With a rectangular mercury foundation and cylindrical water rods, a square lattice is used to build the two-dimensional structure. Performance parameters such as Amplitude Modulation, Contrast Ratio, and Extinction Ratio lend validity to the design. Comsol Multiphysics is used for all related designs and simulations. In phononic integrated circuits utilized in aquatic and medical applications, the design could be crucial.
