Abstract: The use of a triangular grid gives a better relation between element density and inter-element distance, reducing the possibility of grating lobes for large pointing angles in the array. The ...

Abstract: In Lamb wave-based structural health monitoring (SHM), the beamforming of the sensor array plays a crucial role in generating high-quality images. Therefore, it is necessary to analyze the ...
