Electromagnetic radiation

View this topic in
Electromagnetic radiation (often abbreviated E-M radiation or EMR) is a form of energy exhibiting wave-like behavior as it travels through space. EMR has both electric and magnetic field components, which oscillate in phase perpendicular to each other and perpendicular to the direction of energy propagation. (Wikipedia.org)

  • Dielectric properties of tissue-equivalent liquids and their effects on specific absorption rate

    The radio frequency safety of mobile phones has been evaluated in terms of specific absorption rate (SAR). Standard methods for measurement of the SAR, including recipes for tissue-equivalent dielectric liquids, have recently been the subject of discussion among international standards organizations. Standards currently recommend glycol-type liquids as tissue-equivalent liquids for frequencies above 1 GHz. Although the ingredients are specified in the recipes provided, some fundamental information, such as the stability of dielectric properties, remains unclear. We measured the change of dielectric properties with time and with temperature of tissue-equivalent liquids recommended in the standard documents, and evaluated their effects on SAR. The conductivity decreased with increasing temperature in all glycol-type specimens. The permittivity, on the other hand, was almost constant. With the evaporation of water, the permittivity decreased, although the conductivities remained constant. Experimental results proved that dielectric properties are affected by environmental conditions, and that it is inevitably necessary to adjust the dielectric properties regularly, through the addition of ingredients, in order to follow the standards. The SAR values, however, were not affected significantly by the change in dielectric properties; thus, a larger tolerance of the dielectric properties may be acceptable in practical SAR measurements.

  • Implementation of an efficient hybrid method for the analysis of interference in high frequency circuits

    A new Method for Analysis of interference in high frequency has been used for evaluation of the interference of two loop antennas. The method is based on the transmission line matrix (TLM) method augmented with a time-domain integral equation formulation to account for the radiation of equivalent sources and to evaluate the interfering electromagnetic fields. A comparison between this method which is referred as the IRIS method (Interference and Radiation of Internal surfaces) and Different Approaches for the Analysis of Interference has been performed. The result of classical TLM analysis and the IRJS method analysis for Interfering of loop antennas has been represented.

  • Solving 3D electromagnetic scattering and radiation by local multilevel fast multipole algorithm

    As the fastest integral equation solver up to now, multilevel fast multipole algorithm (MLFMA) has been applied successfully to solve electromagnetic scattering and radiation from 3D electrically large object. But for very large scale problems, the storage and CPU time required in MLFMA are still expensive. In this paper, a local multilevel fast multipole algorithm (LMLFMA) is proposed to further speed up the efficiency of MLFMA in conjugate gradient (CG) iteration. In the LMLFMA, only the local interactions between the subscatters are taken into account. And, the interaction regions in iteration are varying adaptively with iterative current density. With decrease of iterative error, iterative current density tends to real one, the interaction regions required are diminishing. When the iterative error is less than a critical iteration error, only the interaction between nearby regions at the finest level is considered. Numerical results show that the LMLFMA has good accuracy, and much better efficiency than traditional MLFMA.
