46. Particle Trajectory Simulations for SCIENA-N : Conversion surface design for an ENA sensor head
University essay from Luleå tekniska universitet/RymdteknikAbstract : This thesis serves as a preliminary design study for the combination of a flight-proven ion optics system (SWIM) with a conversion surface to create a small energetic neutral atom (ENA) sensor. It is planned to use this sensor as ENA sensor for the DFP-SCIENA instrument on Comet Interceptor. READ MORE

47. Detecting Earth-like exoplanets using high-dispersion nulling interferometry
University essay from KTH/Tillämpad fysikAbstract : The detection of Earth-like exoplanets and the characterization of their atmospheres is a challenge one needs to solve to assess their habitability and the presence of life in the universe. If this challenge is still unresolved today, even in the era of giant telescopes, it is mainly because of the very high contrast between these exoplanets and their host star and also their proximity.

48. Towards a high resolution view of infrared line formation
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Observing in the infrared has many benefits, such as seeing through the interstellar dust in the galaxy, easier use of adaptive optics, and better flux ratios for direct observations of exoplanets. Before the infrared spectral range can be utilised for highly accurate stellar spectroscopy there is a need for a better understanding of both stellar modelling and the atomic physics that go into forming spectral lines.

49. Electromagnetic Phase Engineering With Metamaterials
University essay from KTH/Tillämpad fysikAbstract : Metamaterials are artificially designed materials with desired electromagneticresponses for advanced wave manipulation. Their key constituent is often somenoble metal, thanks to its well localized plasmonic effects with highextinction cross section. READ MORE
