A laser interferometer system can be used to measure the straightness of an object. A typical Hewlett-Packard's straightness interferometer system uses a Wollaston prism to split a laser beam traveling along a principal axis into two secondary beams. However, the resolution and the range of the resp.....

Apoptosis, also called programmed cell death, is a very important cellular process that plays a vital role in maintaining the normal physiological function of the organism. It must be precisely regulated in order to maintain the proper functioning of our body. At present, there exist a variety of te.....

A RFID (Radio Frequency Identification) tag with an electromagnetic band gap substrate is introduced to improve the performance of the RFID tag. The electromagnetic band gap substrate acts as a reflector to reflect electromagnetic wave emitted from RFID antenna. This reflected phase of electromagnet.....

This invention discloses an alternative approach of electrically tuning silicon-based waveguide-coupled microresonators that employs photoaligned liquid crystals as cladding layers. Planar optical microresonators that partially confine light and support sharp optical resonances have long been demon.....
