This paper introduces a novel phononic crystal structure and proposes a new type of resonator for achieving acoustic XOR logic gates. Simulation results demonstrate the feasibility of implementing two-input and four-input acoustic XOR logic gates using the proposed structures.
The paper introduces a 2D square lattice phononic crystal structure, with a nylon matrix and molybdenum rods as inclusions. Initially, a new type of resonator, called a triangle resonator, was designed, each of which acts as a two-input acoustic XOR logic gate. Then, a four-input acoustic XOR logic gate is presented by combining these resonators. Simulation results indicate that the realization of two-input and four-input acoustic XOR logic gates is possible using the structures we have proposed. In order to analyze the proposed acoustic XOR logic gates, the transmission spectrum is calculated using the finite element method (FEM).
