Influence of reflected radiation waves caused by large mode field and large refractive index mismatches on splice loss evaluation between elliptical-hole lattice core holey fibers and conventional fibers [PDF]

open access: yes, 2013
When the mode field and refractive index mismatches between two spliced fibers are small, the splice loss is generally evaluated by calculating an overlap integral without reflection waves.

Optimal PV array configuration for extracting maximum power under partial shading conditions by mitigating mismatching power loss

open access: yesCSEE Journal of Power and Energy Systems, 2020
The grid-connected or standalone PV central inverter architecture comprises of several PV modules which are connected in different ways to form the PV array. The power generation capability of the PV array is mainly affected by partial shading conditions (PSC).
