Overview

This work demonstrates a novel 3D probe improving image fidelity in near-field scanning microwave microscopy, suggesting potential for advanced electromagnetic studies.

Key Points

  • The aim is to enhance imaging resolution in near-field scanning microwave microscopy using a novel 3D probe design.
  • Developed a 3D NSMM probe with a split-ring resonator and vertically extended metallic bars.
  • Utilized full-wave numerical simulations to extract the field-spread function and analyze its spatial-frequency content.
  • Created an imaging model representing NSMM images as convolutions with the field-spread function.
  • 3D loading improved electric-field localization and fidelity of the images.
  • Convolution-based model showed matching characteristics with measured images and line profiles.
  • The probe operated effectively as a spatial filter, enhancing resolution in imaging applications.
