Advancing Nanoscale Imaging: A 100-GHz Ultramicroscopy System Based on Nonfocusing Zero-Intermediate Frequency Radar Technology

A scattering-scanning near-field microscope, integrated with a 100-GHz zero-intermediate frequency (zero-IF) radar system, is proposed and demonstrated. Near-field imaging with a resolution of 140 nm is achieved through the utilization of a fundamental mixer. The nonfocusing structure simplifies the...
