In this research, a rotating solar still that uses external bottom reflectors was experimentally investigated. The solar still and reflectors have the capability to shift their angle with respect to the south and the reflectors have the capability to shift their angle with respect to the horizon. The experiment has been performed in both fixed and rotating states. For the fixed state the solar ...

A highly efficient photonic band edge dye-doped cholesteric liquid crystal (CLC) laser is demonstrated. By sandwiching an active CLC cell within a resonator consisting of two passive CLC reflectors, the lasing efficiency is dramatically enhanced. Theoretical analysis using the improved 4x4 transfer matrix and scattering matrix shows that the band edge laser mode can be supported by the external...

A tunable channel-drop filter as essential component for the wavelength-division-multiplexing optical communication system has been demonstrated, which is based on polymer waveguide Bragg reflectors. For an ordinary Bragg reflector, the filtered signal is reflected toward the input waveguide. Thus an external circulator is required to separate the filtered signal from the input port, though it ...

Dielectric multilayer reflectors that are non-polarizing are an important class of optical device and have numerous applications within optical fibres [1], dielectric waveguides [2] and LEDs [3]. Here we report analyses of a biological non-polarizing optical mechanism found in the broadband guanine-cytoplasm "silver" multilayer reflectors of three species of fish. Present in the fish stratum ar...

We propose a new method for fabricating arrays of colloidal quantum dots color conversion layers (CCLs) with atomic layer deposited (ALD) encapsulation. Semiconductor processes were used to transfer the CCL onto transparent glass substrate. This enables pixels as small 5 μm, and pixel's size pitch can be controlled through semiconductor process mask layout. A dual-color array red-and-green was ...

BGP (Border Gateway Protocol), the Internet's current inter-domain routing protocol, has two modes of operation: eBGP (external BGP, used to exchange routing information between autonomous systems (ASes)), and iBGP (internal BGP, used to propagate that information about external destinations to other BGP routers within an AS). Full-mesh iBGP and iBGP with route reflection are the two most commo...

Corner reflectors are widely applied to the precise monitoring of crustal deformation. As shown in recently, however, the machining tolerance of rectangle trihedral corner reflectors in the production and deploy process often results in the changes of RCS. The Radar Cross Section (RCS) of rectangle trihedral corner reflectors are calculated based on Physical Optics Method (PO), the objective of...
