A new class of electronically beam-steerable corrugated substrate integrated waveguide (CSIW) slot array antenna operating at 26–29 GHz has been developed. The conventional via-based walls waveguides (SIWs) or stub-based CSIWs have replaced with an interdigitated capacitor (IDC) structure to enable reconfigurability. This novel IDC-CSIW is shown a lower transmission loss compared in the literat...

This article presents a new self-powered wireless failure detection method that uses different signal transmission rates from piezoelectric energy harvesters. Reliable sensor network has been challenging due to the power supply issue, often covered by batteries need regular replacement. Piezoelectric harvesting is an excellent option sensors in vibrational environment, but level limited input e...

Signal transduction ATPases with numerous domains (STAND) get activated through inducer-dependent assembly into multimeric platforms. This switch relies on the conversion of their nucleotide-binding oligomerization domain (NOD) from a closed, ADP-bound form to an open, ATP-bound form. The NOD closed form is stabilized by contacts with the arm, a domain that connects the NOD to the inducer-bindi...

Dc-dc power converters are employed in a variety of applications, including power supplies for personal computers, office equipment, spacecraft power systems, laptop computers, and telecommunications equipment, as well as dc motor drives. The input to a dc-dc converter is an unregulated dc voltage Vg. The converter produces a regulated output voltage V, having a magnitude (and possibly polarity...

Nowadays carbon nanoparticles are applied on the island of single electron transistor and Nano-transistors. The basis of single electron devices (SEDs) is controllable single electron transfer between small conducting islands. Based on the important points in quantum mechanics, when a wave passes through several spatial regions with different boundaries, the wave function of the first region di...

A novel hybrid brain-computer interface (BCI) based on the electroencephalogram (EEG) signal which consists of a motor imagery- (MI-) based online interactive brain-controlled switch, "teeth clenching" state detector, and a steady-state visual evoked potential- (SSVEP-) based BCI was proposed to provide multidimensional BCI control. MI-based BCI was used as single-pole double throw brain switch...

This thesis first discusses the design, fabrication, and test results of UHF preamplifier designed to operate from 400 to 500 MHz. The preamplifier integrates a single-pole double-throw (SPDT) switch, tapped-line interdigital filter, balanced lownoise amplifier, and gain stage in a compact, multilayer package. The switch and amplification stages are realized on one layer, and the stripline filt...

Smart phones owe some of their multimode, multiband capabilities to multithrow antenna switches. As mobile handsets evolve, a single antenna switch may handle as many as 10 transmit (Tx) and/or receive (Rx) ports. The challenges facing multithrow antenna switches for these applications are not trivial but, fortunately, solutions exist for managing high throw counts while still maintaining excel...
