“…We can write the scattering component of the DGF for four different scenarios:-(i) Both the transmitter and receiver are inside the body: G (11) s (x, x 0 ); (ii) The transmitter is located inside the body and the receiver is located outside: G (12) s (x, x 0 ); (iii) Both the transmitter and receiver are located outside the body: G (22) s (x, x 0 ); and (iv) The transmitter is located outside the body and the receiver is located inside: G (21) s (x, x 0 ). In the above notation of scattering DGF, the two numbers in the superscript represent the medium where the receiver and transmitter are located in that order, '1' represents the medium inside the body and, '2' represents the free space (medium outside the body).…”

Abstract-Human body will act as a transmission channel in wearable wireless devices in the near future. Inclusion of the body as a transmission channel will see future wireless networks rely heavily on Body Area Networks (BAN) with applications in medical and personal area networks. In order to build BAN devices, it is imperative to model the channel accurately. Channel measurements are important, however, a closer look on the body channel can only be attained through Electromagnetic (EM) propagation modelling. This paper presents a preliminary analytical EM channel model for BAN. Specifically, the dyadic Green's function for a simple cylindrical human body model is used to propose a channel model. Four possible cases are considered, where the transmitter and receiver are either inside or outside of the body. An exact analytical expression is derived for the case where both the transmitter and receiver are outside of the body. This case is then used to show how the received signal power varies around the body, with the receiver at a constant radial distance from the cylindrical axis of the body.

“…An elegant manner of doing this task is using the dyadic Green's function. Dyadic Green's functions have been used in Electromagnetic (EM) theory and have solutions for canonical problems, such as cylinders, multilayered cylinders and spheres [19], [20], [21].…”

Abstract-To monitor health information using wireless sensors on body is a promising new application. Human body acts as a transmission channel in wearable wireless devices, so electromagnetic propagation modeling is well thought-out for transmission channel in Wireless Body Area Sensor Network (WBASN). In this paper we have presented the wave propagation in WBASN which is modeled as point source (Antenna), close to the arm of the human body. Four possible cases are presented, where transmitter and receiver are inside or outside of the body. Dyadic Green's function is specifically used to propose a channel model for arm motion of human body model. This function is expanded in terms of vector wave function and scattering superposition principle. This paper describes the analytical derivation of the spherical electric field distribution model and the simulation of those derivations.
