The organic electroluminescent device (OLED) is a new, superior emissive and very thin flat panel display (FPD). Because of its superior performance in brightness, contrast, color, pixelation, nano-scale structure, wider viewing angle, faster response time for full motion video, low power consumptio.....

The invention relates to circularly polarized (CP) antennas with grating dielectric elements acting as a polarizer to convert a linearly polarized omnidirectional radiation pattern from a monopole antenna to an omnidirectional CP radiation pattern. A prototype with parallelepipeds, having a very wid.....

Axial mode helix antennas are used as RFID base station antennas but the number of winding of helix antennas are at least 10, making them too high for use as base station antennas. To address the problem, an integrated wire elliptical helical antenna with novel cuboids dielectric resonator loading f.....

The invention relates to fast processing techniques designed for enhancing the pictorial contents of digital holograms, without the need to reconstruct the original 3D scene. The hologram is back-projected to a hypothetical 2D image known as virtual diffraction plane (VDP). The VDP is then processed.....
