1. mm-Wave Data Transmission and Measurement Techniques: A Holistic Approach
Sammanfattning : The ever-increasing demand on data services places unprecedented technical requirements on networks capacity. With wireless systems having significant roles in broadband delivery, innovative approaches to their development are imperative. LÄS MER
2. Microwave Transistor Noise Model Extraction Methods and a Non-Contacting Scattering Parameter Measurement Method
Sammanfattning : This thesis has two parts. The first part discuss noise model extraction methods for FETs. The second part describe theory and implementation of a non-contacting S-parameter measurement method. Noise is an important aspect for a circuit designer, because noise generated in the circuit is a sensitivity limiting factor. LÄS MER
3. Measurement Techniques for Characterization of Power Amplifiers
Sammanfattning : In this thesis a sampling time domain measurement system primarily intended for measurements on radio frequency power amplifiers is discussed. The need for such a measurement system is established. Impairments due to non-ideal measurement instruments are discussed as well as methods to compensate for these impairments. LÄS MER
4. Experimental Evaluation of a Microwave Imaging System for Muscle Rupture Detection
Sammanfattning : Injuries to the hamstring muscles are one of the most common injuries in sports such as football, sprinting, and running. Imaging plays a key role in diagnosing and managing athletes with muscle injuries, and particularly magnetic resonance imaging is usually required to diagnose muscle ruptures. LÄS MER
5. Ultra-Wideband Time Domain Measurement Systems for Microwave Tomography
Sammanfattning : As a potential imaging modality for biomedical applications, microwave tomography has attracted a lot of interests in recent years. With microwave tomography, microwave signals are transmitted into the biological tissues and the scattered fields are recorded. LÄS MER
