A Review on Level of Specific Absorption Rate Due to High Power Transmission Lines: Analysis toward Human Position Posture

Abstract

Abstract. The main contribution of this project is the development of a homogeneous model of a man to presents the specific absorption rate (SAR) due to high power transmission line. As a low frequency application under high power transmission line of 50 Hz in electrical engineering, to studies the influence of human's posture on specific absorption rate. This project designs two types of human body which one design uses most cylinder block and another design use brick block where both blocks have a different value of mesh cells. For each design has four types of posture are standing, sitting, arms up and arms out by using Computer Simulation Technology (CST) Studio Software. This analysis does toward for four types of the human position postures because each posture has different value of specific absorption rate (SAR) based on the size of the mesh cells of the design. Based on two designs of the human body, the lowest of the mesh cells value will reduce time to simulate SAR. For each posture has different value of SAR for each part of the human body because the whole human body has different types of tissues. Therefore, the CST studio software uses extremely to simulate the SAR value toward human position posture due to high power transmission line.

Radiation effect of fractal sierpinski square patch antenna

“…There are different approaches to SAR reduction, first approach is implemented by changing the angle of Electromagnetic source in relation to human body such as skin, brain and bone, second approach is investigated using fractal theory to reduce the size of antenna or changing the type of material covering the radiator [8]. SAR is determined mathematically by dividing the product of conductivity with square of the root mean square value of the electric field strength (E) to the volume density in certain tissue [9]:…”
