Project description

The Oskar Klein Centre and the Department of Physics at Stockholm University invites applications for a Postdoctoral fellow focusing on the design and testing of lightweight metamaterial candidates for broadband millimeter-wavelength absorbers to be used by the LiteBIRD satellite.

The successful candidates will be part of the Oskar Klein Centre for Cosmoparticle Physics ( in Stockholm, a rich scientific environment that comprises more than a hundred researchers working in both theory and experiment in the fields of astronomy, astrophysics and particle physics at both Stockholm University and the Royal Institute for Technology.

The OKC hosts a vibrant research program on dark matter, dark energy, transient and multimessenger astrophysics, structure formation, and related particle physics questions. Postdoctoral associates are also welcome to participate in Scientific Programs at Nordita, the Nordic Institute for Theoretical Physics, which bring together groups of leading experts to work on specific topics for extended periods. Stockholm, which spreads across a beautiful archipelago located in the Baltic Sea, offers easy access to a diverse set of nature activities and cultural experiences.

Main responsibilities

We are advertising a 2-year postdoc employment, funded by the Swedish Space Agency, to work on the development and testing of mm-wavelength absorbers for the LiteBIRD satellite. The project involves further development of existing technologies while optimizing for broadband and wide-angle absorption, low mass, and cryogenic robustness.

The custom materials will be tested against well-known absorber solutions under a range of conditions mimicking those that will likely be seen in a 4th-generation CMB satellite, LiteBIRD led by JAXA, observing at frequencies covering 40-400 GHz. We anticipate that progress on this work effort will be discussed during weekly meetings within the LiteBIRD Collaboration.
