Abstract
Vibration is a source of energy that can be beneficial or harmful based on the application. Vibration can affect the function of any structure; however, Ceramic matrix composite (CMC) is one of these structures. Whereby less studies have been concentrated on study its function specially when electromagnetic wave (microwave) exposed on its surface to perform its designed function. To address this concept, SiC composite has been fabricated which is designed to have a transparent characteristics to microwave. External vibration had been applied on its surface to monitor how much influence could nanoscale amplitude vibration damage the microwave interaction. The source of vibration was applied from piezoelectric and the vibration was monitored via laser doppler vibrometer, while the microwave band was generated from the network analyzer at a range of 8.2 to 12.4 GHz. The results revealed that vibration can assist significantly microwave penetration inside the composite and increase the transparent characteristic of the composite. This considers important for portable ceramic composite designed to interact with electromagnetic wave (radar) which covered with such structure.
