In this paper, a novel silicon-on-insulator (SOI) lateral-double-diffused metal-oxide-semiconductor field-effect transistor (LDMOSFET) is presented. Changing charge distribution leads to lower electric field crowding and increased breakdown voltage (VBR). For modifying charge distribution, a metal region (COLUMN) and an air layer inside the transistor are utilized. On the other the floating-body effect and impact ionization generate excess holes that are amplified by the parasitic bipolar junction transistor (BJT) in SOI-LDMOSFET that degrade the transistor performance.

Static analysis is increasingly used by companies and individual code developers to detect bugs and security vulnerabilities. As programs grow more complex, the analyses have to support new code concepts, frameworks and libraries. However, static-analysis code itself is also prone to bugs. While more complex analyses are written and used in production systems every day, the cost of debugging and fixing them also increases tremendously.

In this letter, a compact pattern reconfigurable filtering microstrip antenna is presented with broad bandwidth, good selectivity at the passband edge, and flat gain frequency response. The pattern reconfigurable filtering antenna has four resonant modes which can be adjusted independently, three of them are created by multi-mode resonator (MMR) and the other one is by radiator. The four resonant modes are well distributed in desired band and the resonant mode of radiator is located between the first two resonant modes of MMR.

This paper presents an overview of Unidirectional

Loop Metamaterial (ULM) structures and applications. Mimicking

electron spin precession in ferrites using loops with unidirectional

loads (typically transistors), the ULM exhibits all the

fundamental properties of ferrite materials, and represents the

only existing magnetless ferrimagnetic medium. We present here

an extended explanation of ULM physics and unified description

 

of its component and system applications.

Advances in Wireless Sensor Network Technology (WSN) have provided the availability of small and low-cost sensor with capability of sensing various types of physical and environmental conditions, data processing and wireless communication. In WSN, the sensor nodes have a limited transmission range, and their processing and storage capabilities as well as their energy resources are limited. Triple Umpiring System (TUS) has already been proved its better performance on Wireless Sensor Networks. Clustering technique provides an effective way to prolong the lifetime of WSN.
