多维表面波形式主义的推广的基础上的分析已经产生了一些一般性的结果磁电声表面波。对于机械固定、电封闭和磁开放的表面，当压磁效应和压电效应同时存在时，可能产生一种新的亚音速表面波。详细分析了机械自由面作为电磁边界条件函数的情况。从来没有两个以上的亚音速解决方案。一个表的构造，使我们能够在知识的基础上的解决方案的数量为一个特定的情况下的边界条件，作出预测和具体的报表有关的表面波解决方案的存在和他们的数量为其他边界条件。
An analysis based on a generalization of the many-dimensional surface wave formalism has yielded a number of general results for magneto-electroacoustic surface waves. For a mechanically clamped, electrically closed and magnetically open surface a new subsonic surface wave may come into existence when piezomagnetic and piezoelectric effects are present simultaneously. The case of a mechanically free surface as function of electrical and magnetic boundary conditions has been analyzed in detail. There are never more than two subsonic solutions. A table is constructed which allows us, on the basis of knowledge of the number of solutions for a particular case of boundary conditions, to make predictions and specific statements concerning the existence of surface wave solutions and their number for other boundary conditions.
