Design and analysis of a novel dielectric loaded helical antenna
(World Scientific and Engineering Academy and Society (WSEAS) Press, 2009)
Helical antennas have been a popular antenna configuration for various applications for its simple structure. This work describes the study on a novel, custom-shaped dielectric loaded helical antenna incorporated on an ...
Oscillatory dynamical switching system of bulk ferroelectrics
(Science Publications, 2005)
This study gives a detailed account of calculation of the bulk ferroelectric (FE) oscillatory dynamical system switching for first and second-order phase transition, respectively. All the formalism is delineated in the ...
Analysis of Bulk Second-Order Ferroelectric Switching in Oscillatory Dynamical System
(Kolej Universiti Kejuruteraan Utara Malaysia, 2004)
A detailed analysis of polarization reversal in bulk for second-order ferroelectric (FE) phase transition material in the framework of the Landau model is presented. We focus on the changes of polarization P and its switching ...
The physics of Tsunami: basic understanding of the Indian Ocean disaster
(Science Publications, 2005)
This study gives a simple physics explanation behind the Indian Ocean earthquake, called December 26th‘s Tsunami. The explanation based on physics energy conservation and wave properties have been used to understand this ...
The effect of conductor line to meander line antenna design
(Institute of Electrical and Electronics Engineering (IEEE), 2008)
In this paper, the meander line antenna (MLA) have been designed to operate at 2.4-GHz for WLAN application. Two different designs of meander line antenna are investigated, without conductor line and with conductor line. ...
A dual band planar monopole antenna with inverted-M parasitic plane
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
Introduction of parasitic plane as additional radiator helps to produce desired resonant frequencies, while helping to minimize the size of the antenna. A dual-band monopole antenna with parasitic plane is designed to ...
Oxidation behaviour of low carbon steel in natural water
(Oriental Science Publishing Co, 2002)
Natural water pollution has been identified as a potential danger to metallic materials used under service conditions. Sea water and lake water foulants have adequate corrosive environment due to chemical ingredients ...
A MIMO LMS adaptive equalization approach in simulated radar emission
(Institute of Electrical and Electronics Engineering (IEEE), 2006)
MIMO technology has attracted a lot of attention in the area of wireless communications such as radar applications, in term of increasing the spectral efficiency. This research paper will present the model of Simulated ...
An investigation of Rayleigh distribution in reverberation chamber
(Institute of Electrical and Electronics Engineering (IEEE), 2006-09-12)
Amplitude fluctuations in signals received over mobile radio channels are typically modeled by a Rayleigh distribution. The field statistics in the volume of the enclosure are shown to correspond to the Rayleigh statistics ...
