ABSTRACT. In this paper a parametric modeling technique for a fast polynomial extraction of the physically relevant parameters of inductively coupled RFID/NFC (radio frequency identification/near field communication) antennas is presented. The polynomial model

Enhancement of Immunoassay s Fluorescence and Detection Sensitivity Using Three-Dimensional Plasmonic Nano-Antenna-Dots Array
free download

ABSTRACT Protein detection is universal and vital in biological study and medical diagnosis (eg, cancer detection). Fluorescent immunoassay is one of the most widely used and most sensitive methods in protein detection (Giljohann, DA; Mirkin, CA Nature 2009,

Validation of a One-Antenna Reverberation-Chamber Technique for Estimating the Total and Radiation Efficiency of an Antenna
free download

ABSTRACT 1 Because of the statistical environment created inside reverberation chambers, they are ideally suited for performing radiated power measurements of either an antenna or a device under test, and as such, it is possible to determine their efficiencies. In previous

Coherence effects and broadening in medium-induced QCD radiation off a massive antenna
free download

A bstract Studies of medium-induced QCD radiation usually rely on the calculation of single- gluon radiation spectrum off an energetic parton traversing an extended colored medium. Recently, the importance of interference effects between emitters in the medium has been

A Compact Triple Band Antenna for a Wireless USB Dongle
free download

ABSTRACT A compact monopole antenna possessing triple resonance (f1, f2, f3) characteristics for (USB) dongle applications is presented. The resonance characteristic f1 is determined by the overall length of the antenna. The monopole antenna acts as the main radiator for f3

Microwave Ablation Treatment of Liver Cancer with a 2,450-MHz Cooled-shaft Antenna: Pilot Study on Safety and Efficacy
free download

ABSTRACT To evaluate efficacy of microwave ablation in a primary clinical study, sixty patients (44 men, 16 women; mean age 53 years) with 96, 1-8 cm (mean 3.20 0.17 cm) liver cancers were treated with 2,450-MHz internally cooled-shaft antenna. Complete ablation (CA) and

Dual Band Defected Ground Microstrip Patch Antenna for WLAN/WiMax and Satellite Application
free download

Abstract A microstrip patch antenna for Wi-Max and GSM application is proposed. The antenna has a frequency bandwidth of 1.24 GHz (4.6053 GHz–5.8481 GHz) for WLAN and Wi-Max and 1.04 GHz (6.124 GHz–7.16 GHz) for Satellite application. The microstrip

PoS (QNP2012) 151 In-medium antenna radiation in t-channel
free download

Most of the efforts made in recent years have concentrated on the medium modification for the inclusive gluon spectrum off a single hard parton [1, 2, 3, 4, 5, 6]. One clear limitation of these formalisms is the lack of coherence effects between different emitters which is a

The radiation pattern of a QCD antenna in a dilute medium
free download

A bstract Radiative interferences in the multi-parton shower is the building block of QCD jet physics in vacuum. The presence of a hot medium made of quarks and gluons is expected to alter this interference pattern. To study these effects, we derive the gluon emission
