A Comprehensive Review of Midrange Wireless Power Transfer Using Dielectric Resonators

International Journal of Antennas and Propagation, 2021
Magnetic resonant coupling (MRC) is one of the techniques that are widely used in wireless power transfer (WPT) systems. The technique is commonly used for enhancing distance while maintaining power transfer efficiency (PTE).

Fast tuning of superconducting microwave cavities

, 2008
Photons are fundamental excitations of the electromagnetic field and can be captured in cavities. For a given cavity with a certain size, the fundamental mode has a fixed frequency {\it f} which gives the photons a specific "color". The cavity also has a

Strongly Enhanced Sensitivity in Planar Microwave Sensors Based on Metamaterial coupling

, 2017
Limited sensitivity and sensing range are arguably the greatest challenges in microwave sensor design. Recent attempts to improve these properties have relied on metamaterial- (MTM-) inspired open-loop resonators (OLRs) coupled to transmission lines (TLs)
