“…In designing antennas for wireless communication, it is very important to analysis SAR values of the proposed antenna. Several investigation has been performed about SAR reduction [10][11][12][13]. In this paper, SAR analysis has been performed, where the reference power of the wireless device is set to 500mW.…”

In this paper, a new wideband Circular monopole antenna is proposed for Wireless communication. Commercially available finite difference time domain (FDTD) based software Computer Simulation Technology (CST) microwave studio has been adopted in this investigation. A wide frequency bandwidth of 3.25 GHz (1.65 GHz to 4.9 GHz.) has obtained in measurement. The operating frequencies of the proposed antenna are GSM-1800, GSM-1900, UMTS, Bluetooth (2400-2800) MHz, WLAN (2400-2485) MHz and WiMAX frequency bands. The antenna has been printed on FR-4 (lossy) Substrate material with relative Permittivity of 4.6 and thickness of 1.6 mm. The computational results has been validated the measured one. In addition, the electromagnetic absorption analysis has been investigated for the proposed antenna.

“…Faruque et al further investigated with two concentric triangular rings resounding electric response by stacking, but it was evident that the longitudinal size is increased and unconvinced for design and manufacturing. Faruque et al explored a new shape of square metamaterial and reduced the SAR. The design is easy for fabrication but exhibits lower performance compared with a Triangular shape.…”

Specific Absorption Rate (SAR) is an inevitable parameter to be considered for various RF dosimetry evaluations in the field of biomedical engineering. There is a much concern in exposure studies as they have a significant impact on the social and health issues in the recent global community. SAR measures the absorption of electromagnetic radiation of RF from devices in an exposure area. The significance of SAR parameter has been awakened in broad areas of technology and even considered in the design of radiating structures from biomedical devices such as MRI to also popular mobile phones. Researchers have explicated the constant interaction of electromagnetic field interactions with biological systems. The advancements in technology pose a grave concern about the impact on human health. This paper intends to undertake an extensive survey of the various current investigations done with SAR in different scenarios with possible radiating structures and also focus on exposure areas on the human body. The SAR depends on estimation parameters that are analyzed and discussed. Further, the paper will analyze comparatively the facets of implied Methodologies in SAR computation. The parametric evaluation of SAR paves the way for a requirement reduction of SAR parameter. The paper discusses current reduction methodologies and its primary advantages and details possible setbacks. The analysis indicates a requirement of the specific radiation structure for a particular area of exposure of concern, followed by a need of ideal reduction methodology.

“…For several authors the interest in relative motion was aiming at an approximate treatment of the gravitational two-body problem in General Relativity [6] [7] [8], see also [9], but the scope of the present paper is strictly limited to Minkowski spacetime and special relativity. We have in mind the two-body conservative dynamics of directly interacting point particles; the field carrying interaction is supposed to be eliminated.…”

In Minkowski spacetime, we consider an isolated system made of two pointlike bodies interacting at a distance in the nonradiative approximation. Our framework is the covariant and a priori Hamiltonian formalism of "predictive relativistic mechanics", founded on the equal-time condition. The issue of an equivalent one-body description is discussed. We distinguish two different concepts: on the one hand an almost purely kinematic relative particle, on the other hand an effective particle which involves an explicit dynamical formulation; several versions of the latter are possible. Relative and effective particles have the same orbit, but may differ by their schedules.
