Comparative study between measurement and predictions using geometrical optics and uniform theory of diffraction for case of non-line-of-sight (NLOS) in indoor environment
(Springer Science+Business Media New York, 2013-08)
This paper describes the investigation and comparison of the accuracy of a deterministic model for a WLAN system in the indoor environment. The measurement system consisted of a spectrum analyzer and a log-periodic antenna. ...
Modeling of coaxial slot waveguides using analytical and numerical approaches: Revisited
(Hindawi Publishing Corporation, 2012)
Our reviews of analytical methods and numerical methods for coaxial slot waveguides are presented. The theories, background, and physical principles related to frequency-domain electromagnetic equations for coaxial waveguides ...
Experimental determination of the performance of rice husk-carbon nanotube composites for absorbing microwave signals in the frequency range of 12.4-18 GHz
(EMW Publishing, 2013)
Composites of rice husks and carbon nanotubes (RHC-NTs) are an innovation in improving the absorption of microwave signals. Rice husks, which are an agricultural waste material, have been found to possess a significant ...

Dielectric spectroscopy of pharmaceutical drug (Paracetamol) dosage in water
(IEEE Conference Publications, 2013-12)
This paper discuss about the dielectric measurement on different concentration of pharmaceutical drug using Agilent 85070E High-Temperature and Slim form probe. A microwave dielectric measurement is set up to measure dosage ...
Rubber tire dust-rice husk pyramidal microwave absorber
(EMW Publishing, 2011)
Rubber tire dust-rice husk is an innovation in improving the design of pyramidal microwave absorbers to be used in radio frequency (RF) anechoic chambers. An RF anechoic chamber is a shielded room covered with absorbers ...
