Calibration software for higher-resolution dielectric resonator imaging of larger-scale film samples and a database of reference data in Gwyddion format

Dielectric resonators (DRs) are one of the three microwave macroscopic material measurements technologies, considered and further developed within the MMAMA project. The main purpose of this Deliverable is to propose a new software technique for enhancing the resolution of DR measurements without the need to reduce the DR’s head and increase the operating frequency. The Deliverable contains: - a brief review of inherent limitations of DR measurements, in terms of sample size and spatial resolution, as well as earlier approaches for their overcoming, - field - theoretical derivation of a new technique for resolution enhancement, by calibrating the raw scan of material surface with pre-simulated electromagnetic (EM) field patterns in the DR, - measurement and calibration workflow implementing the proposed technique, - "virtual laboratory" in Matlab environment, with testing models and procedures for validation of the workflow, - example results for virtual and real - life samples. Besides the main purpose of enhancing the DR measurements per se, it is believed that the concept of resolution improvement by de-embedding raw measurements with known (pre-simulated) EM field patterns helps bridging the gap between the macroscopic and microscopic measurement technologies considered in the project
