Physics of Magnetic Multilayers and Devices at Millimeter Wave Frequencies
Abstract
Microwave devices are widely used in both military and civilian communications systems. During the last decades, we have witnessed incredible progress in high frequency semiconductor electronics and, in particular, a movement towards the synthesis of different electronic components into integrated circuits. The obvious obstacle, however, to an increased use of microwave and millimeter wave technology is the lack of advances in magnetic structures at high frequencies, 10-100 GHz. The main goal of this project was to look at both fundamental and applied physics relating to high frequency (10-100 GHz) waves in magnetic materials and devices. We have developed three different signal processing devices:, tunable band stop and band pass filters and tunable phase shifters based on the ferromagnetic metals. We demonstrated operation of these devices at frequencies up to 30 GHz in low magnetic fields.
