본 논문에서는 신체 내 무선 통신을 지원하기 위해 상체 횡단면에서의 전파 특성을 이론적으로 분석하고자 한다. 분석적 평가에서는 인체가 2/3 근육에 해당하는 균일한 조직으로 구성된 무한 길이의 손실 유전 원형 실린더로 구조화되어 있다고 가정합니다. 실린더 내부와 외부의 각 산란 전기장 공식은 소스 전류가 실린더 표면에 수직 방향 또는 실린더 축에 수평 방향을 가질 때 인체를 포함한 전파 환경에서의 산란 특성에 대해 유도됩니다. 공식의 신뢰성을 확인하기 위해 2.45 GHz에서의 전체 전계 분포를 FDTD(유한차분 시간 영역) 방법의 결과와 비교합니다. 각 전류 방향에서 일반적인 산란 특성과 전체 전파에 대한 영향이 추정됩니다. 또한, 동작 주파수, 인체 반경, 광원과 인체 사이의 거리 변화에 따른 산란 및 총 전기장 세기를 평가하여 전파 특성을 조사하여 체내 전파 장치 설계에 도움을 줍니다. 상체와의 채널.

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.
