Course Title Advanced Topics in Microwave Engineering
Course Code EE-948
Credit Hours 3-0
Pre-Requisutes UG level courses including Microwave Engineering, Electronics, Wave propagation and antenna design
Course Objectives The course is intended to provide in-depth and detailed knowledge in Microwave Engineering required for students of EE with majors in Communication Engineering. The course comprises of following modules;A. RF Analysis, Measurements, Microwave circuit design (MCD) and MMIC: To Develop a detailed understanding about the advanced analysis techniques for RF and microwave network analysis. Existing and advanced systems will also be studied, and where possible practical applications in present and future communication receivers will be studied. Basic measurement systems will also be covered. B. Nanotechnology: To prepare for the next generation of electronic devices, this module teaches the theory of current, voltage and resistance from atoms up. To describe electrons at the nanoscale, an introduction to the principles of quantum mechanics, including quantization, the waveparticle duality, wave functions and Schrödinger's equation would be covered. Then the electronic properties of molecules, carbon nano-tubes and crystals, including energy band formation and the origin of metals, insulators and semiconductors would be deliberated. C. Ultra High Speed Microwave Devices (12 hours): High speed semiconductor devices unit provides a comprehensive overview of all aspects of monolithic Microwave Integrated Circuits(MMICs) from active and passive components to the fabrication technology.D. Diode Detectors, Mixers and Oscillators The module will focus on nonlinear circuit elements and will give indepth analysis of state of the art devices.E. Solar Cells This module will give extensive exposure of underlying physical phenomenaand principles of normal Silicon based and compound semiconductor based high-efficiency multijunction solar cells.
