Microwave techniques encompass experimental and analytical methods that exploit electromagnetic radiation in the microwave frequency range (typically 0.3–300 GHz) for material characterization, signal manipulation, and device evaluation. These techniques include microwave spectroscopy, vector network analysis of scattering parameters, cavity perturbation methods, and time-domain reflectometry. They are used to determine complex permittivity, permeability, dielectric loss, and conductivity, as well as to study resonant modes, dispersion, and non-linear responses in materials and components. Microwave techniques are fundamental in characterizing high-frequency circuits, antennas, metamaterials, superconducting devices, and in probing condensed matter systems under controlled temperature, magnetic field, or pressure conditions.
The electronic and magnetic properties of two-dimensional materials both have strong potential for technological applications. Researchers have long assumed that they are distinct phenomena, but Illinois Grainger engineers ...
