Abstract
Collection mode near-field microscopy is demonstrated using a 10.56GHz (X-band) frequency illumination. Imaging of a standing evanescent microwave was experimentally used to evaluate the capabilities of the microscope. The microscope functionality was validated by imaging near field interactions of different systems of dipole-like resonances. We prove that those microscope images contain near-field information by presenting numerical modeling of dipole-like resonant interactions. The model makes use of an analytic Dyadic Green's which is based in the near-field electrostatic approximation. We propose that this microscopy technique can be used, with certain limitations, as a check for 2D mapping of designed (spoof) surface plasmon at microwave frequencies.
