Este artigo tenta analisar teoricamente as características de propagação na seção transversal da parte superior do corpo para suportar comunicações sem fio no corpo. A estimativa analítica assume que o corpo humano é estruturado como um cilindro circular dielétrico com perdas com comprimento infinito que consiste em tecido uniforme equivalente a 2/3 de músculo. Cada formulação de campo elétrico de dispersão dentro e fora do cilindro é derivada para características de dispersão no ambiente de propagação, incluindo o corpo humano, quando a corrente da fonte tem a direção vertical para a superfície do cilindro ou a direção horizontal para o eixo do cilindro. Para confirmar a confiabilidade da formulação, as distribuições totais do campo elétrico em 2.45 GHz são comparadas com os resultados pelo método de diferenças finitas no domínio do tempo (FDTD). Em cada direção da corrente são estimadas as características gerais de espalhamento e a influência na propagação total. Além disso, a partir das intensidades de espalhamento e campo elétrico total avaliadas com as variações de frequência de operação, raio do corpo humano e distância entre uma fonte e o corpo humano, características de propagação são investigadas para auxiliar no projeto de um dispositivo para propagação no corpo. canal com a parte superior do corpo.

Abstract: This paper attempts to analyze theoretically the propagation characteristics in the transverse section of upper body to support on-body wireless communications. The analytical estimation assumes that the human body is structured as a lossy-dielectric circular cylinder with infinite length that consists of the 2/3-muscle equivalent uniform tissue. Each scattering electric field formulation inside and outside of the cylinder is derived for scattering characteristics in the propagation environment including the human body when the source current has the vertical direction to the cylinder surface or the horizontal direction to the cylinder axis. In order to confirm the reliability of the formulation, total electric field distributions at 2.45 GHz are compared with the results by the finite-difference time-domain (FDTD) method. In each current direction, general scattering characteristics and the influence on the total propagation are estimated. Furthermore, from scattering and total electric field intensities evaluated with the variations of operating frequency, radius of the human body, and distance between a source and the human body, propagation characteristics are investigated to assist in the design of a device for on-body propagation channel with the upper body.
