Hybrid computational scheme for antenna human body interaction
A new hybrid method of moments (MoM)/finite-difference time-domain (FDTD), with a sub-gridded finite-difference time�domain (SGFDTD) approach is presented. The method overcomes the drawbacks of homogeneous MoM and FDTD simulations, and so permits accurate analysis of realistic applications. As a...

| description | A new hybrid method of moments (MoM)/finite-difference
time-domain (FDTD), with a sub-gridded finite-difference time�domain (SGFDTD) approach is presented. The method overcomes
the drawbacks of homogeneous MoM and FDTD simulations, and so
permits accurate analysis of realistic applications. As a demonstration,
it is applied to the short-range interaction between an inhomogeneous
human body and a small UHF RFID antenna tag, operating at
900 MHz. Near-field and far-field performance for the antenna are
assessed for different placements over the body. The cumulative
distribution function of the radiation efficiency and the absorbed power
are presented and analyzed. The algorithm has a five-fold speed
advantage over fine-gridded FDTD. |
