The increasing demand for multifunctional devices, the use of cognitive wireless technology to solve the frequency resource shortage problem, as well as the capabilities and operational flexibility necessary to meet ever-changing environment result in an urgent need of multiband wireless communications. Spectral filter is an essential part of any communication systems, and in the case of multib...

Since the publication of our first paper on the microwave-accelerated metal-enhanced fluorescence (MAMEF) bioassay platform technology in 2005 (Aslan and Geddes, Anal Chem 77:8057–8067, 2005), we have been repeatedly asked to comment on the advantages of “microwave heating” with plasmonic nanostructures over conventional heating for bioassays by many of our colleagues in the community. We note ...

There is considerable concern in the numerical weather prediction (NWP) community that the Advanced Technology Microwave Sounder (ATMS) is merely being built to the noise specifications of the Advanced Microwave Sounding Unit (AMSU) and the Microwave Humidity Sounder (MHS). Since the AMSU/MHS have greatly exceeded the noise specification, the NWP community is worried that the ATMS in fact would...

─ Upgrading successful processes of microwave-assisted organic synthesis to the level of industrial technology is currently slowed by difficulties in experimental development of largescale and highly-productive reactors. This paper proposes to address this issue by developing microwave chemistry reactors as microwave systems, rather than as black-box-type units for chemical reactions. We sugges...

The method of processing biomass of various kinds by microwave-assisted pyrolysis has been presented. The fast pyrolysis process, characterized by rapid heating of the feedstock in the absence of oxygen and rapid cooling of the volatile intermediate reaction products, is one of attractive liquid biofuel production methods. However, the pyrolysis still requires improvements as regards the proces...

ABSTRACT-Wireless Local Area Network (WLAN) that uses the IEEE 802.11 standard and WiMAX (Worldwide Interoperability for Microwave Access) that uses the IEEE 802.16 standard are networks that we are want to explore. description of the existing wireless technology Wi-Fi and WiMAX, and try to compare Wi-Fi (IEEE 802.11) and WiMAX (IEEE 802.16). Wireless Local Area Network (WLAN) uses of IEEE 802....

he development of technology in the THz frequency band has seen rapid progress recently. Considered as an extension of the microwave and millimeter wave bands, the THz frequency offers greater communications bandwidth than is available at microwave frequencies. The development of sources and detectors for this frequency range has been driven by other applications such as spectroscopy, imaging, ...

Five sample digestion procedures were evaluated for the determination of Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, P, S, Sr, and Zn in food samples by inductively coupled plasma atomic emission spectrometry. The 5 procedures include dry ashing at 500 degrees C, wet digestion with HNO3-HClO4, microwave digestion with HNO3, microwave digestion with HNO3-H2O2, and microwave digestion with HNO3-H2O2-HF. Fo...

Indian high-ash coal contains alpha-silica components of the mineral matter. When coal is transported in the form of a slurry, alpha-silica adds to the settling properties of coal and enhances erosion of pipelines. As such any technique that will contribute to changing the characteristics of mineral matter by selective demineralization is bound to supplement the knowledge of coal slurries in th...

We report experimental and analytical results of a fiber-optic link that supports simultaneous transmission of baseband data and subcarrier multiplexed control-data channels. A novel transmitter design is used to optoelectronically combine baseband and subcarrier channels onto the optical carrier using a differential Mach–Zehnder (MZ) interferometer modulator. Microwave direct detection of the ...
