Internship | Metasurface based Polarization Scramblers for Space Instruments
About this position
Radiometric instruments have different detection sensitivities for different light polarization states. To avoid losing the photons associated to a signal with a polarization for which the instrument is less sensitive, a polarization scrambler (a device for light depolarization) is positioned at its entrance, therefore making the instrument able to detect the signal independently of its polarization. The implementation of scramblers with “traditional” optical components results in bulky/complex devices. On the contrary, the use of nanopatterned metasurfaces could considerably simplify the realization of a scrambler with a consequent reduction of very important factors for space technology like volume, weight and costs.
What will be your role?
The student will undertake the following activities:
- Get familiar with the concept of polarization scramblers and their current state-of-the-art for space instruments.
- Study the theory and get introduced to the design of optical nanopatterned metasurfaces.
- Assess different concepts of metasurface based scramblers.
- After the selection of a preferred solution, he will proceed at its design/optimization, using electromagnetic modelling tools available at TNO.
During the internship project, student will be assisted by TNO staff members working on optical metasurfaces and space instruments.
What we expect from you
The candidate should have a good background knowledge of Electromagnetic Theory and Optics.
The candidate should preferably have some experience with:
- commercial electromagnetic modelling tools (e.g. ANSYS HFSS and/or ANSYS LUMERICAL and/or CST STUDIO and/or COMSOL).
- programming in MATLAB/PHYTON.
This internship is best suited for MSc final projects, with a duration of at least 9 months.
