We present a simple configuration incorporating a single polarization-sensitive phase-only liquid crystal spatial light modulator (LC-SLM) to facilitate polarization-insensitive spatial light modulation. The polarization-insensitive configuration is formed by a polarization beam splitter (PBS), a polarization-sensitive phase-only LC-SLM, a half-wave plate (HWP), and a mirror in a loop structure...

Results are reported of some-tests aimed at determinmg the effect of sidewall compresslon III a " two-dimensional " lntslce having combined external/internal compression and a design Mach number of 2.2. Sidewall oompresslon results from the chamfers that are necessary to provide thickness for the splitter plate separatmng the two units of a twin cell intake. The results suggest that the maximum...

In order for the promise of terahertz (THz) wireless communications to become a reality, many new devices need to be developed, such as those for routing THz waves. We demonstrate a power splitting router based on a parallel-plate waveguide (PPWG) T-junction excited by the TE1 waveguide mode. By integrating a small triangular septum into the waveguide plate, we are able to direct the THz light ...

We report the first year on-orbit performance results for the Galaxy Evolution Explorer (GALEX), a NASA Small Explorer that is performing a survey of the sky in two ultraviolet bands. The instrument comprises a 50 cm diameter modified Ritchey-Chrétien telescope with a 1.25 field of view, selectable imaging and objective grism spectroscopic modes, and an innovative optical system with a thin-fil...

A polarization beam splitter (PBS) based on a giant-reflection to zero-order (GIRO) grating is presented. The GIRO grating is a simple binary diffraction grating with parameters chosen such that the excited optical modes in the grating interfere constructively and destructively at the respective interfaces. This interference results in high-zero-order reflection (>99%) with a high polarization-...

The polarization-dependent photon-number squeezing of 1.5 dB from a grating feedback locking quantum-well laser in a cryostat has been experimentally detected with a balanced homodyne detector including an imperfect nonpolarized-beam splitter. The great influence of the birefringence induced at low temperature on the determination of the shot-noise-limit and on the detection of photon-number sq...

For flow-induced vibration of a rounded-square cylinder under the effect proximity interference by stationary splitter plate downstream, numerical study is presented for various corner-radius R(0.1−0.5), reduced velocity U*(2−12.5), cylinder-plate gap G*(0.3,2.0), Reynolds number Re = 100, mass ratio M*=1, damping coefficient ζ=0.005, plate-length L*=1, and plate-thickness t*=0.05. R, vortex-in...

A microstrip power splitter with band-pass responses is presented in this paper. The design is based on square open loop resonator topology. This filtered power splitter does not require quarter wavelength transformers and will result in a smaller size than a conventional Wilkinson power divider with integrated band-pass filter. It is a two-way equal power splitter with fifth order band-pass fi...

In aerodynamics study, whenever there is a flat/blunt face, it will result in the maximum drag effect on flat body. these types of problems, splitter plates have found significant role reducing force. The plate separate/bifurcate flow at front face present study aims to find fluid flows over body by varying length plate. pressure and Mach number effects near surface Also, crucial for higher vel...
