16. Design and characterisation of terahertz Schottky diode harmonic mixers
Abstract : Efficient, compact, and reliable terahertz frequency converters preferably operating at ambient temperature are crucial for stabilising far-infrared optical sources. This thesis focuses on the design and characterisation of terahertz Schottky diode harmonic mixers for frequency stabilisation of quantum-cascade lasers. READ MORE

20. Ground based measurements of upper atmospheric CO and H2O using microwave radiometry
Abstract : Long series of continuous measurements of middle and upper atmospheric constituents are needed to be able to understand the anthropogenic influence on the atmosphere. Phenomena like ozone depletion and the enhanced greenhouse effect are examples where the role of human activities has to be well investigated in order to make the right decisions of necessary changes in our way of life.
