On-Chip Solutions for Future THz Imaging Spectrometers

The mysteries of the early Universe are largely enshrouded in dust, product of the violent process of star formation. Due to the vast distances of our Universe, infrared light emitted by the heated dust back in those early stages can still be observed today, which has been observed to contribute to about half of the total cosmic background...

On the Development of a Lens Phased-Array at 100GHz

This thesis is concerned with a first time demonstration of a high frequency scanning lens phased­-array with dynamic steering. Such phased­-array could provide the high gain, wide bandwidth, and steering capability that the next generation of wireless ap­plications requires. The phased-­array development was divided into three distinct parts....

Conformal Phased Array for DISTURB

Mankind becomes ever more reliant on wireless technology like mobile communications, navigation and radar. This development has resulted in more sensitive receivers, but this increased sensitivity also has increased the susceptibility of these receivers to interference from external sources. One of these sources that is known to disrupt...

Early design of the MOSAIC antenna

The work of this thesis has been carried out in the framework of the project Multi-Object Spectrometer with an Array of superconducting Integrated Circuits, also known as MOSAIC. The aim of this instrument is to resolve the Cosmic Infrared Background (CIB) from a 10 m diameter ground-based telescope. MOSAIC will be the first multi-object three...

UWB Antennas and MIMO Antenna Arrays Development for Near-Field Imaging

UWB radar is the most promising radar system for the future. In addition, by combining the UWB and array signal processing, one can obtain 3-D images of the objects for classification and identification, which is very useful in many applications. To achieve high-resolution real-time 3-D imaging radar, two essential items are missing in the...

Non-Invasive Electromagnetic Ablation of Female Breast Tumors

Breast cancer is the most common malignant tumor among women today. Available techniques for treating breast cancer often introduce strong side effects. The non-invasive electromagnetic ablation of breast tumors has a lot of potential, because it can provide a quick treatment modality without introducing harmful side effects. In this project we...
