A comparative study on the effect of quasi-block hand model specific absorption rate measurement
Suzanna H., Ronald; M.F.A., Malek; Hassan, S.I.S; Muhammad Solihin, Zulkefli; Mohd Hafizuddin, Mat; Ee Meng, Cheng, Dr. (2011)A candy bar mobile phone with Planar Inverted-F Antenna (PIFA) operating at 900 MHz and 1800 MHz is simulated with two models of quasi-block hand homogeneous and inhomogeneous. Maximum Specific Absorption Rate (SAR) is ... -
Effect of load variations in DC-DC converter
Husna, A. W. N.; Siti Fatimah, Siraj, Prof. Madya. Dr.; Mahathir, H. Mat (Institute of Electrical and Electronics Engineers (IEEE), 2011-09-20)The effect of load variations on the stability of the open-loop DC-DC boost converter is investigated in this paper. Mathematical model of boost converter is derived using state-space averaging technique and perturbation ... -
The influence of human head model wearing metal-frame spectacles to the changes of SAR and antenna gain: Simulation of frontal face exposure
