Metallization of a 3D printed cavitiy for imaging

In this paper, we propose a metallized 3D printed cavity for K-band imaging and investigate the effect of metallization type on mode diversity and image reconstruction. The 3D printed cavity acts as a frequency-diverse aperture and is capable of imaging objects in an all-electronic manner utilizing computational imaging techniques. We demonstrate that metallization material choice can increase the mode diversity by 90.8%, significantly improving imaging.
