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.eninfo:eu-repo/semantics/closedAccesssonic flat lenssonic crystalsfocusingExperimental observation of far-field and near-field focusing in a sonic crystal flat lens in airArticle221110.1088/0957-0233/22/11/1151052-s2.0-80054758746Q2WOS:000296563500033N/A
