1. Spectrometers and receiver systems for ground, balloon and satellite based (sub)millimetre radio astronomy
Sammanfattning : .... LÄS MER
2. Stacking of interferometric data at sub-millimeter and radio wavelengths
Sammanfattning : Understanding the procceses of galaxy evolution require observational constraints on the physical properties of galaxies at different times in the history of the Universe. Large and deep surveys at visible and near-infrared wavelengths have, during the past decade, been used to produce extensive catalogues of high-redshift galaxies, spanning a large range of the history of the Universe.

3. Millimetre wave waveguide enclosed grid frequency multipliers and imaging
Sammanfattning : The utilisation of the THz spectrum ( 0.3-10 THz ) is hampered by fundamental difficulties in generating power at these frequencies. LÄS MER
4. Compact and Efficient Millimetre-Wave Circuits for Wideband Applications
Sammanfattning : Radio systems, along with the ever increasing processing power provided by computer technology, have altered many aspects of our society over the last century. Various gadgets and integrated electronics are found everywhere nowadays; many of these were science-fiction only a few decades ago. LÄS MER
5. HBV frequency multiplier 2D arrays and application
Sammanfattning : The utilisation of the THz spectrum ( 0.3-3 THz ) is hampered by technological difficulties to generate power at these frequencies. LÄS MER
