摘要: This paper reviews the ideal configuration of air-coupled transducers and compares it with that actual ones. reveals main problems present nowadays in design construction these transducers, consequently, some solutions are proposed: 1. Modification selection criteria for matching layers, a proposal new kind impedance materials 2. New strategies to cope inevitable non-ideal features design.
