| The fundamental operation of radar is transmission and reception of electromagnetic waves. When the waves strike an object, some portion is reflected, some transmitted and some absorbed by the object. If the received or absorbed parts are bigger then reflected, the object may not be dedected by the radar. In this study, it was aimed to produce radar absorbing materials with this principle especially for certain military applications focused on defence and security. Magnetic zinc oxide particles were synthesized by sol-gel. They were embedded to a polymeric matrix with different loading level to see the concentration dependence. The particles were characterized by X-Ray diffraction. Under applied magnetic field, the produced composites exhibited the hysteresis loops of the ferromagnetic behavior with vibrating sample magnetometer. In addition, radar absorbing test was applied as a primary objective of this research with a network analyzer. It was concluded that Fe doped zinc oxide composites have electromagnetic properties which indicate potential application in radar absorbing applications. |
