Innovative system for the aerial altitude platform sky mesh network in isolated areas
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
Communications service needs to keep pace with technological progress to meet the needs of users, In terms of enhancing the quality of service (QoS) and reach the end- system. An isolated area is the project goal because ...
SCPS solution for heterogeneous networks for isolated areas: a novel design approach
(ICIC International, 2012)
This research presents an innovative system that has capability to prove the technical feasibility and advantages of a joint radio frequency (RF) and free space optic (FSO) system with a synchronized self-trace directional ...
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 ...
Effect of lattice constant on band-gap energy and optimization and stabilization of high-temperature In xGa 1 -xN quantum-dot lasers
(Springer US, 2012-07)
We analyze the effect of the lattice constant on the band-gap energy of In x Ga1−x N and optimize the structure of the device with a separate-confinement heterostructure. To vary the lattice constants, we change the In ...

(Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
In this paper, 2.45 GHz compact peanut-shape
antenna suitable for bio-telemetric tablet system is proposed. In order to make a compact antenna, multi-layer substrate and
shorting pin method are used. The specific absorption ...
Study of Malaysian-sized hand phantom for GSM900/1800 application
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
A simple block hand model with the size of an adult Malaysian hand is suggested to substitute the existing hand phantom of European size. The hand is set up with a Standard Anthropomorphic Mannequin (SAM) head and a candy ...
A comparative study of simple geometrical head phantoms on specific absorption rates for simulations and measurements at 900MHz
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
In this paper, a dipole antenna operating at 900 MHz is simulated to examine the most suitable simple geometrical head phantoms for specific absorption rate (SAR) simulations
and measurements. The numerical analysis was ...
Ferroelectric materials in microstrip patch array antenna
