NANO-ZINC OXIDE FOR SAW DEVICES Zinc oxide as a piezoelectric material , has a strong electromechanical coupling coefficient, so that ultrasonic transducer, Bragg deflector , spectrum analyzer , high-frequency filter, high-speed optical switches and micro-machined on a wide range of purposes. These devices in high-capacity , high-speed optical fiber communication wavelength division multiplexing , fiber-optic phase modulation , anti-radar dynamic frequency measurement , electronic monitoring, satellite mobile communications , parallel optical information processing , such as civilian and military application of a wide range of fields, such as in higher than the 1.5GHz frequency range with the high-frequency low-loss filter for mobile communication systems are becoming the one of the most critical components , Zinc oxide is to produce the material of choice for such high-frequency filter . Zinc oxide not only has the absorptive capacity of electromagnetic waves , but also absorb visible light and infrared , to use it for stealth materials , not only in a very wide range of frequency bands to avoid radar detection , but also played the role of infrared stealth . This stealth material the development and application of weapons systems is to improve the penetration ability of survival and an effective means of one of the national defense construction is very important .
