Higher specific absorption rate (SAR) values have been found in children when exposed to RF sources. It is worth noting that mass densities of each of the tissues is always used as of that of an adult person, despite the evident difference of tissue dielectric values due to the difference of water contents in each development stage. Some researchers have reported that children may exhibit higher SAR...
In this paper, we investigate the physical-layer security for a wireless two-hop relay network in the presence of channel estimation errors when estimating the channel state information (CSI) of the main links (from the source via relays to the destination) and wiretap links (from the source and relays to the eavesdropper). The eavesdropper can not only overhear the confidential signals transmitted...
Age-dependent dielectric properties of tissues have been calculated based on a number of interpolation equations in the frequency range of 0.4–10GHz. The proposed method for calculating age-dependent dielectric properties is based on mapping the existing measured data [1] for pigs to those of humans using weight/age plots. The method provides growth curves relating the dielectric properties of both...
This paper applies the Radial Basis function (RBF) collocation method to compute the eddy current magnetic field coupled with conductor movement. Because of the linear characteristic of the RBF collocation matrix equation, the unknown magnetic vector potential could be easily decoupled and directly expressed in moving coordinate systems without model recast. This offers a great convenience to deal...
This paper presents a review on the improved magnetron modelling which was achieved by exploiting a newly-developed software tool to automate the model definition in command-line solvers. The software was designed to work with the renowned MAGIC command-line software, by introducing pre-processing functions which assist the user to enter the required parameters using a 3D graphical interface. This...
