“…The close proximity of human body with a high dielectric constant and loss are known to have a detrimental effect on antenna input impedance and efficiency. Other research areas on wearable technology concentrate on wireless body-area networks (BAN) [3,4], wearable systems carried in clothing [5], and realization of fabric antennas [6] or stretchable interconnections [7,8]. Research on medical applications concentrate on the biomedical data with less emphasis on the bodyworn wireless link [9].…”

Abstract-The effect of human body on inkjet-printed flexible singlelayer transmission lines in immediate proximity of body is investigated by simulations and measurements up to 9 GHz. A multiline extraction method is used to obtain effective material parameters allowing detailed analysis of body effects. Already at 1 mm distance from the body, the line properties converge toward the free-space values. However, at smaller distances and in direct contact with the body, often required in biosensor applications, there is a significant change in characteristic impedance and increase in losses. The results of the paper can be used to evaluate the body effects at different frequencies and at different small distances from the body.

Abstract-An improved finite-difference time-domain (FDTD) method is proposed for predicting transient responses of coaxial cables which are placed in an electrically large metallic cabin with arbitrary slots and circular windows on its wall. By integrating nodal analysis, multi-conductor transmission line (MTL) equation and FDTD method, we are able to accurately capture electromagnetic interference (EMI) effects on the cables. Our developed algorithm is verified by calculating frequency-dependent transfer impedance of coaxial cables together with induced currents. Numerical calculations are further performed to show the near-end coupled current responses of braided and tubular cables, respectively, and the effects of incident directions and polarizations of the illuminated electromagnetic pulse are both taken into account.

Abstract-Single-crystalline silver filaments with periodic pearlchain-like structures are fabricated by electrodeposition without using any templates, surfactants, and additives. Simulations demonstrate that excited surface waves may sustain on silver pearl chains in middle infrared (Mid-IR) range. The propagation features of surface waves on the silver filaments indicate the structure application for Mid-IR wave transmittance.
