In this paper, the classic finite-difference time-domain (FDTD) method is reviewed and novel schemes are implemented for modelling metamaterials at various frequency bands. Numerical results are presented in comparison with those from analytical and numerical approaches. The possibility of their applications in antenna and microwave engineering are also be discussed.
In this paper the on-body radio channel is statistically analysed at 2.45 GHz and analytically and numerically modelled at the same frequency applying different techniques. The channel exhibits great variability due to body movements with path loss data behaving in different manors depending mainly on the freedom of the communication link between transmitting and receiving antenna. Simple and accurate...
