Özet

This experimental study demonstrates intensity maps of far-field focusing using a two-dimensional triangular lattice sonic crystal and intensity maps of near-field focusing using a two-dimensional square lattice sonic crystal for various scatter materials. Besides, the paper presents an experimental method to estimate the effective refraction index of far-field flat lenses. The author introduces the experimental setup developed for the research and discusses the results obtained.
