Density Tapering for Sparse Planar Spiral Antenna Arrays

Increasing demands for mobile internet access have led to exponential developments in mobile communications technologies. The next generation mobile technology is expected to exploit electronic beam steering and to have a higher operating frequency to facilitate a higher bandwidth. This places a heavy burden on the base station antenna arrays,...

Efficiency analysis and design methodology of hybrid propulsion systems

A hybrid propulsion system features both a diesel engine and an electric motor for propulsion. The degrees of freedom with power generation raise the question how this division between power can be optimised in such a way that the engines are running with their optimal fuel efficiency. A generalised method to determine the power generation for...

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...
