1. Photonic terahertz-wave generation, radiation and quasioptical integration
Abstract : This thesis deals with the uni-travelling-carrier photodiode (UTC-PD) based photonic generation of terahertz waves, antenna designs for the terahertz radiation and a novelcatadioptric lens for quasioptical integration.The ongoing and accomplished research work on the UTC-PD, its limitations and optimisation scopes for attaining higher bandwidth and higher output power have been discussed.

2. Energy Transfer Processes and Quenching Pathways in Lanthanide Complexes: The Role of Structural Changes
Abstract : Due to their unique magnetic and luminescent properties, trivalent lanthanides (Ln(III)) have been widely utilised in cellular imaging. Ln(III) luminescence is usually sensitized by a light-harvesting ‘antenna’, a chromophore that can transfer the excitation energy to the Ln(III). READ MORE

3. Photonic THz Generation and Quasioptical Integration for Imaging Applications
Abstract : This thesis deals with the analysis and optimisation of the uni-travelling-carrier photodiode (UTC-PD) for continuous-wave generation in terahertz (THz) frequencyrange. Photonic THz generation using UTC-PDs is extremely promising as it offers wide tunability, adequate output power and room temperature operation. READ MORE

4. Electromagnetic Modelling for the Estimation of Wood Parameters
Abstract : Spiral grain in trees causes trouble to the wood industry, since boards sawn from trees with large grain angle have severe problems with form stability. Measurements of the grain angle under bark enable the optimisation of the refining process. READ MORE
