Large-scale transient simulations of breast cancer tumour´s reflections using a 31-element conformal array

This paper demonstrates large-scale electromagnetic simulations of a real microwave imaging system for breast cancer detection. In particular we present calculated transient scattering responses from a tumour in a breast phantom modelled with dispersive materials. The responses are obtained from the full-scale numerical model of the 31-element antennas array. Two different numerical methods are considered in this work, i.e. the Finite Integration Technique (FIT) method implemented in a commercial solver and an inhouse developed Finite-Volume Time-Domain (FVTD) code.
