1. Theory of transformation optics and invisibility cloak design
Abstract : Research on metamaterials has been growing ever since the first experimental realization of double negative media. The theory of transformation optics provides people with a perfect tool to make use of vast possibilities of the constitutive parameters for metamaterials. READ MORE

2. Matrix Algebra for Quantum Chemistry
Abstract : This thesis concerns methods of reduced complexity for electronic structure calculations. When quantum chemistry methods are applied to large systems, it is important to optimally use computer resources and only store data and perform operations that contribute to the overall accuracy.

3. Scattering on the Timoshenko Beam. Direct and Inverse Problems in the Time Domain
Abstract : This thesis concerns the use of time domain methods for treating direct and inverse scattering problems for flexural waves on beams. The Timoshenko equation is used throughout to describe the behaviour of such waves. READ MORE

4. The Voice Source in Speech Communication - Production and Perception Experiments Involving Inverse Filtering and Synthesis
Abstract : This thesis explores, through a number of production andperception studies, the nature of the voice source signal andhow it varies in spoken communication. Research is alsopresented that deals with the techniques and methodologies foranalysing and synthesising the voice source. READ MORE

5. Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications
Abstract : The aim of this thesis is to solve an inverse source problem. The approach is based on an integral representation together with the extinction theorem. Both a scalar and a full-wave integral representation are implemented and solved by a Method of Moment procedure. READ MORE
