2. Development of SiC MESFET Based MMIC Technology
Abstract : A SiC MESFET based MMIC process has been successfully developed. This technology has its main potential in high power microwave circuits. It will offer the benefits of the high integration seen in GaAs MMIC at the same time as it will offer the benefits of the high voltage operation seen in Si LDMOS and Si BJTs. READ MORE

3. Analysis of Resistor-Loaded Bow-Tie Antennas for Ground Penetrating Radar Applications
Abstract : Ground penetrating radar (GPR) systems are increasinglybeing used for the detection and location of buried objectswithin the upper regions of the earth's surface. Numericalsimulation of such systems plays an important role in thedevelopment of GPR hardware and signal processingtechniques. READ MORE

5. Spin dependent transport in Co nano-scale tunnel junctions
Abstract : Ferromagnetic tunnel junctionshave been fabricated, measured and theoretically described. Anoverview of the Julliere model, and Slonczewski's model todescribe the resistance change due to di®erent orientationof the magnetization between the magnetic electrodes(magnetoresistance) is given.
