Because of an improvement of wireless communication technologies, cables are taken away step by step from an electrical equipment. Now, a power cable is the last wire connected to the equipment. Therefore, wireless power transfer (WPT) technology is desired. Conventionally, microwave power transfer and magnetic induction have been used for this purpose. Microwave power transfer technology utili...

Wafer-level packaging (WLP) technology offers novel opportunities for the realisation of highquality on-chip passives needed in RF front-ends. IMEC proposes thin-film WLP technology in combination with 90nm CMOS as a cost-effective approach to integrate RF and microwave systems. The potential of this technology is assessed by means of two demonstrator sub-circuits: a low-power voltage-controlle...

The concept of nonthermal microwave effects has received considerable attention in recent years and is the subject of intense debate in the scientific community. Nonthermal microwave effects have been postulated to result from a direct stabilizing interaction of the electric field with specific (polar) molecules in the reaction medium that is not related to a macroscopic temperature effect. In ...

Microwave energy is a superior alternative to several other thermal treatments. Extraction techniques are widely employed for the isolation of bioactive compounds and vegetable oils from oil seeds. Among the different and new available techniques, microwave pretreatment of seeds is a simple and desirable method for production of high quality vegetable oils. Microwave pretreatment for oil extrac...

Microwave generated plasma have found a number of technology based applications these include application in emission spectroscopy of the determination of elemental composition, production of catalytic materials and the area of coating technology. There is the possibility of using the high temperatures associated with plasmas for waste processing technologies. To date there has been limited amo...

Silicon technology has progressed over the last several years from a digitally oriented technology to one well suited for microwave and RF applications at a high level of integration. Technology scaling, both at the transistor and back-end metallization level, has driven this progress. CMOS technology is ideally suited for low-noise amplification and receiver applications, but the fundamental b...

We demonstrate the application of molecular rotational spectroscopy to measure the conformation isomerization rate of vibrationally excited pent-1-en-4-yne (pentenyne). The rotational spectra of single quantum states of pentenyne are acquired by using a combination of IR-Fourier transform microwave double-resonance spectroscopy and high-resolution, single-photon IR spectroscopy. The quantum sta...

WiMAX: An analysis of the existing technology and compare with the cellular networks. Abstract Broadband access technology has significant influences in the telecommunication industry. Worldwide interoperability for microwave access (WiMAX) is a broadband wireless technology which brings broadband experience to a wireless context. There are two different types of broadband wireless services. On...
