Abstract
An 
band microwave filter consisting of two microwave cavities attached and orthogonal to each other with a YIG-GGG-YIG sample in a sandwich configuration has been designed and tested. Normally the two cavities do not couple electromagnetically to each other, but do couple through the sandwich configuration. The sandwich configuration is placed in between the two cavities so that there is one YIG film in each cavity. The amount of coupling can be varied by: (1) the magnitude of the static field, 
, and (2) the angle between 
and the film surface. The parallel layering of the two YIG films is essential in the improved performance of the microwave filter.
