Editor´s Note

Summary form only given, as follows. Microwave acoustics is becoming a very important area for microwave engineers and work in this area is presently being carried out at various laboratories. The area of microwave acoustics is a natural one for microwave engineers to get involved in because of its similarity to classical microwave theory and techniques. The purpose of this issue is to bring to the attention of the microwave engineer the work being done in this area and the problems that require further investigation. It is hoped that this issue will bring out the relevance between classical microwave theory and techniques and microwave acoustics. The effort to organize this issue was enormous, and we were very fortunate to have Dr. A.J. Bahr, a well-known contributor in this area, as Guest Editor. His tremendous efforts in organizing this issue, as well as his other contributions as Chairman of the G-MTT Technical Committee on Microwave Acoustics, are greatly appreciated.
