A folding concept has been developed which allows a precision membrane aperture to be elastically stowed with a very high compaction ratio without creasing. The lack of creasing is extremely important when the membrane is used in RF or diffractive op

Thermal contact resistance inhibits heat removal from electronic components, and can result in overheating, performance degradation, and failure. However, determining and/or verifying contact resistance can be challenging since it is dependent upon s
