On the Use of Reconfigurable Space-Time Metasurface Enclosures for Microwave Imaging
Mario Phaneuf, Puyan Mojabi
Abstract
The use of space-time metasurfaces as microwave imaging (MWI) system enclosures (casings) is discussed. In contrast to commonly used MWI enclosures, these can be reconfigured so as to implement different boundary conditions for data collection and processing schemes. In particular, the use of a space-time-modulated metasurface enclosure to implement two seemingly contradictory boundary conditions for MWI, namely, open space and perfect electric conductor conditions, are discussed along with quantitative imaging results.
