Abstract
The acoustic transmission response of plates perforated with fractal subwavelength holes array is studied. The Sierpinski Carpet pattern is used as fractal geometry. Ultrasound transmission spectra show that each iterative Sierpinski Carpet has the characteristic peaks and dips of the lattice constant of each array that formed the pattern. The angular dependency of the transmission coefficients shows a complex interplay between Fabry–Perot resonances, Wood anomaly minima and Lamb modes.
