Metasurfaces for Wave-front Modulation Across the Electromagnetic Spectrum from Microwaves to Optical Frequencies
conference paper
In this paper, we present an overview of several research activities on metasurfaces, over a very broad frequency range, from microwaves up to the infrared and visible spectrum, performed at TNO in the last years. A first example is a metasurface for Radar Cross Section (RCS) reduction, controlled by light. This concept is particularly interesting also because it combines metasurfaces operating at different frequencies. Other examples are spectro-polarimetric filters for Earth Observation Instruments and for miniaturized spectro-polarimetric cameras; plasmonic metasurfaces for optical superabsorbers in the visible spectrum, and reconfigurable spectral filters in the Short-Wave Infrared (SWIR) spectrum, for trace gasses detection space spectrometers, based on Compressive Sensing (CS) techniques.
