—A simple and powerful micro-particle swarm optimizer (PSO) is presented. For high dimensional optimization problems, the proposed PSO needs only a small population to outperform the standard particle swarm optimizer (PSO) that uses a larger population. This superior performance is confirmed by simulation results for different high dimensional test(More)
A novel expanded tip wire (ETW) catheter antenna is proposed for microwave ablation for the treatment of atrial fibrillation (AF). The antenna is designed as an integral part of coaxial cable so that it can be inserted via a 6F catheter. A numerical model based on the rotationally symmetric finite-difference time-domain technique incorporating the(More)
1. Introduction Microwave imaging is an electromagnetic (EM) inverse scattering application that has played an important role in various fields such as radar, remote sensing and biomedical applications. By subjecting the object under investigation (OUI) to microwave radiation, the measured scattered fields are used to produce images which are maps of(More)
The clustering of propagating signals in indoor environments can influence the performance of multiple-input multiple-output (MIMO) systems that employ multiple-element antennas at the transmitter and receiver. In order to clarify the effect of clustering propagation on the performance of indoor MIMO systems, we propose a simple and efficient indoor MIMO(More)
,Ah$rmciBoth Ray tracing and practical measurements hiwe confirmed existence o f clustering of signals during propagation in an indoor environment. In this paper we propose a hybrid MlMO channel model that allows illcorporation of spatial correlation into modeling of indoor environments involving the use of multiple antenna elements. The MlMO model i s(More)
