摘要

本文简要介绍了超声辐射模理论的发展历程。RMT起源于电磁学,它已被证明在波导和不连续领域是非常有效的。在超声波中,RMT仅在十年前才进入市场,并且已经被证明在描述声音与不连续的相互作用方面非常有效,例如在板上的台阶,液体楔,板的末端等等。二维各向同性介质的RMT的发展很可能已经接近尾声。本文列举了目前取得的一些结果。预计未来十年将进一步扩展到更复杂的媒体。

The ultrasonic radiation mode theory
This paper describes a short history of the radiation mode theory (RMT) in ultrasonics. The RMT originates from electromagnetism where it has proved to be very efficient in the field of wave guides and discontinuities. In ultrasonics the RMT made its entrance only a decade ago and has already proved to be very efficient in describing the interaction of sound with discontinuities such as a step on a plate, a liquid wedge, the extremity of a plate and much more. It is likely that the development of the RMT for 2D isotropic media has come almost to an end. This papers lists some of the results obtained so far. Further extensions to more complicated media re to be expected the coming decade.
