Six-Plate and Hybrid-Dielectric Capacitive Coupler for Underwater Wireless Power Transfer
IEEE Transactions on Power ElectronicsThis article presents a novel design approach for a six-plate horizontal coupler for underwater capacitive power transfer (CPT). The coupler comprises four power transfer plates and two shielding plates that effectively prevent external interference and ...

Mismatched directional couplers
Optics Letters, 1990Various twin-core couplers composed of mismatched optical fibers are capable of complete power transfer over lengths only moderately longer than their matched analogs. Examples include tapered and piecewise-continuous mismatched couplers. These linear couplers also provide insight into the mechanism of nonlinear coupling because nonlinearity induces ...

Two types of multimode fiber couplers made from plastic-clad fibers are described: (1) cross type couplers with coupling efficiencies from 30 dB to 50 dB depending on the crossover angle; and (2) parallel type couplers with low transmission loss and coupling efficiencies from 15 dB to 30 dB depending on the coupling length.

Design of High-Directivity Wideband Microstrip Directional Coupler With Fragment-Type Structure
IEEE transactions on microwave theory and techniques, 2015A novel design for a microstrip wideband directional coupler is proposed by using fragment-type structures. The use of a fragment-type structure may provide satisfactory flexibility and excellent performance.
