Conventionally, frequency tuning is achieved by changing the capacitance of a tank using varactor. However, it is more power efficient to minimize the capacitance of the tank and adjust the inductance for frequency variation. Therefore, the need for a variable inductor arises.A novel integrated vari.....

This improved material relates to novel planar materials having band gap properties, and in particular to such materials formed with fractal patterns. Band gap materials are ideal for shielding electromagnetic (EM) radiation as they have a gap in the transmission band thus blocking transmission of E.....

With the development of microelectronic, micromachine and drug delivery device, there has been increasing demand for micro- or nanopumps. Micropumps are one of the most important microfluidic components, which have been mainly made by the micromachining technology. Different micropumps have their sp.....

Organic light-emitting diode (OLED) displays are thinner, lighter, power saving, and are more responsive than liquid crystal displays (LCDs). Present designs of double-sided displays involve physically putting two displays in one back-to-back assembly. This limits OLEDs to very few commercial applic.....

Thin-film transistors (TFTs) are used in the construction of active-matrix devices like liquid-crystal displays (LCDs), organic light emitting diode (OLED) displays, and image sensors. TFTs based on amorphous silicon suffer from low operating speed and lack of a p-type device, making it difficult to.....
