Infrared sensing plays a crucial role in modern space instrumentation, enabling the detection of weak thermal and spectroscopic signals in scientific payloads for astrophysics, planetary exploration, and satellite-based earth observation.
Space missions such as ISO, Herschel, Webb, and SPHEREx demonstrate the continued strategic importance of infrared technologies across a broad range of wavelengths and scientific goals. In this context, plasmonic nanoantennas offer a promising route to enhance light–matter interaction at subwavelength scale and to support the development of compact, high-performance detectors.
This PhD project proposes the design, simulation, fabrication, and characterization of plasmonic antennas for infrared detection in space applications. The activity will include numerical electromagnetic modelling, cleanroom fabrication, and optical/electrical characterization aimed at optimizing resonance control, absorption efficiency, and coupling to detector elements.
The project is expected to provide new design strategies for antenna-assisted infrared detectors compatible with the constraints of future spaceborne instruments, including miniaturization, integration, and performance enhancement.
