21. Spin Torque Oscillator Modeling, CMOS Design and STO-CMOS Integration
Abstract : Spin torque oscillators (STOs) are microwave oscillators with an attractive blend of features, including a more-than-octave tunability, GHz operating frequencies, nanoscale size, nanosecond switching speed and full compatibility with CMOS technology. Over the past decade, STOs' physical phenomena have been explored to a greater extent, their performance has been further improved, and STOs have already shown great potential for a wide range of applications, from microwave sources and detectors to neuromorphic computing.

22. RF and Noise Optimization of Pseudomorphic inP HEMT Technology
Abstract : The InGaAs-InAlAs-InP high electron mobility transistor (InP HEMT) is the electronic device utilized for the highest frequency and/or the lowest noise applications known to date for analog transistor-based circuits. Hence it is of both scientific and technological interest to explore the InP HEMT for even further improvement in device performance. READ MORE

23. Characterization of Microwave Transistors for Robust Receivers and High Efficiency Transmitters
Abstract : The next generation of integrated transceiver front-ends needs both robustlow noise amplifiers and high power amplifiers on a single-chip. The AluminiumGallium Nitride / Gallium Nitride (AlGaN/GaN) High Electron MobilityTransistors (HEMT) is a suitable semiconductor technology for this purposedue to its high breakdown voltage and high electron mobility.

24. Remote sensing of clouds and precipitation using active and passive microwave observations
Abstract : Global observations of clouds and precipitation are of great importance for weather prediction and the monitoring of the climate. Nonetheless, the currently available record of global observations does not constrain the properties of clouds very well owing to the inherent limitations of the observation systems used to produce them.
