A dynamically reconfigurable wave-chaoticmetasurface antenna is presented to perform computational polarimetric microwave imaging. The metasurface is synthesized using sparsely distributed sub-wavelength supercells, each consisting of two orthogonally separated complementary electric inductive-capacitive (cELC) unit-cells.These super-cells radiate selectively (under PIN diode control)in both vertical and horizontal polarizations, ensuring that the synthesized wave-chaotic modes are polarimetric in nature.Leveraging the dynamically modulated waveform diversity ofthe incoherent wave-chaotic radiations from the metasurface antenna, polarimetric imaging is computed in the near-field region at K-band frequencies and the polarimetric responses ofspecific targets are retrieved.
