This paper presents a new whole-body averaged specific absorption rate (SAR) estimation method based on the cylindrical fields scanning technique. The aim of this study is to achieve experimentally an estimation of whole-body averaged SAR in human models due to plane wave exposure using the radiation-field scanning technique.

This article introduces a measurement methodology for the evaluation of specific absorption rate (SAR) MIMO systems (multiple-input and multiple-output) in which relative phases between antennas are rapidly changing very short durations.

The purpose of this study is to establish a whole-body averaged specific absorption rate (WB-SAR) experimental estimation method using the total power absorbed by humans; a cylindrical-external field scanning technique is used to measure the radiated RF (radiofrequency) power. This technique is adopted with the goal of simplifying the exposure dosimetry of humans of different postures and/or si...

INTRODUCTION Many wireless systems are more and more present in daily life. More than 5 billions of people over the world are nowadays using devices emitting electromagnetic fields. This paper presents an analysis of the specific absorption rate (SAR) induced by an incident EM plane wave in different fetuses embedded in a homogeneous women model. Moreover, the influence of this homogeneity on t...

Specific Absorption Rate (SAR) designates the electromagnetic power density deposited per unit mass of biological tissues. This paper presents a new approach where SAR calculation for mobile phones is based on a parametric reconstruction of the E-field distribution in the phantom to assess rapid SAR measurements, by means of an ellipsoidal model. The estimation of its parameters is achieved by ...

We report the advantage of exchange coupling between a magnetically soft (MnFe2O4) and hard (Co0.7Zn0.3Fe2O4 Co0.5Zn0.5Fe2O4) magnetic phase to increase specific absorption rate (SAR) in inductive heating. All samples were synthesized by hydrothermal method. While saturation magnetization (Ms) two composite nanoparticles is approximately 1.1 times higher Ms single-component, SAR more 2 than tho...

In this paper, we compare different models for the interpolation and extrapolation of the SAR (Specific Absorption Rate) in biological tissues produced by an electromagnetic source. The configuration under study is a spherical benchmark at 900 MHz. The spatial distribution of the SAR is well-known [1] for this configuration. Based on these data, one can do a virtual measurement on a realistical...

This paper proposes a microstrip patch antenna for 2.45 GHz Industrial Scientific Medical (ISM) band Wireless Body Area Network (WBAN) applications. To enhance the front-to-back ratio (F/B) and specific absorption rate (SAR), an electrically coupled LC resonator is introduced. The overall dimensions of the proposed antenna are 54 mm × 45 mm × 2.4 mm and it has a gain of over 1 dBi for the entir...

INTRODUCTION A multi-antenna transmitter, e.g. in Multi-Input Multi-Output (MIMO) systems, will be implemented in the user equipment (UE) of mobile communication systems in the near future [1]. Applying the standardized procedures [2][3] for obtaining the maximum average Specific Absorption Rate (SAR), which is an evaluation index for RF exposure to human, requires the measurement of the three-...
