This research uses computational fluid dynamics (CFD) to perform a two-stage optimization of power output in multiple vertical-axis wind turbines (VAWT) with straight blades. In the first stage, four configurations are evaluated and optimized utilizi

In recent years, LTE in unlicensed spectrum (LTE-U) has become more and more popular all around the world. Since available resources in licensed bands are becoming scarcer, we need to find out more spectrum. However, one of the biggest chall

As the photonic crystal fibers (PCFs) are fabricated, it is hard to modulate their optical properties to function as tunable optical devices. To introduce tunable optical properties into the PCFs, one can infiltrate tunable-index materials,

We have theoretically investigated the birefringence and loss properties of the selectively liquid-filled photonic crystal fibers with the liquid asymmetrically infiltrated into one-line air holes along x -axis. A high birefringence value B = 1.74 ×

A photonic crystal fiber (PCF) with high-quality graphene nano-particles uniformly dispersed in the hole cladding are demonstrated to passively mode-lock the erbium-doped fiber laser (EDFL) by evanescent-wave interaction. The few-layer graphene nano-

We demonstrate an optically tunable fiber attenuator by selectively infiltrating a photoresponsive liquid crystal mixture into a photonic crystal fiber. With 4-second blue-laser irradiation, the optically tunable attenuation can be increased to 26 dB

A novel light-controllable long-period fiber grating (LPFG) is demonstrated by making use of a PCF infiltrated with a photoresponsive liquid crystal (LC) mixture consisting of nematic LC molecules and light-sensitive 4-methoxyazobenzene (4MAB). With

A variable birefringence effect has been observed with 1D PMMA surface gratings on a gold film substrate. By changing the operation wavelength on the Au film, the birefringence value Δn(eff) changes from positive to negative. The result verified tha
