Wireless local area networks (WLANs) are considered to be the fastest growing communication technology because of their low cost and high data rates. In this paper the effect of interference caused by Bluetooth devices and Microwave ovens on the performance of 802.11b WLANs is investigated. Results show that 802.11b WLAN are not affected severely while operating in the presence of a Bluetooth l...

In recent years SIC has metamorphisized from an R&D based materials system to emerge as a key substrate technology for a significant fraction of the world production of green, blue and ultraviolet LEDs. Emerging markets for S i c homoepitaxy include high-power switching devices and microwave devices. Applications for heteroepitaxial GaN-based structures on S i c substrates include laserss and m...

We propose a procedure for transferring the state a microwave qubit via a transmission line from one resonator to another resonator, with a theoretical efficiency arbitrarily close to 100%. The emission and capture of the microwave energy is performed using tunable couplers, whose transmission coefficients vary in time. Using the superconducting phase qubit technology and tunable couplers with ...

Spectral hole-burning (SHB) technology is considered for >10-GHz instantaneous bandwidth signal-processing applications. In this context we report on what is believed to be the first demonstration of a SHB microwave spectrometer. A set of gratings engraved in a SHB crystal is used to filter one sideband of the optically carried microwave signal. The setup is confined to narrow-bandwidth operati...

There is a huge development in mobile communications in Europe and consequently, the need for training engineering students in microwave design is growing. We present here some students projects aimed at designing microwave subsystems in MMIC and HMIC technology, for different wireless communications applications. They have been performed at LHOG/ENSERG (INPG), France. The capabilities and cons...
