Abstract :
An accurate model of dielectric strut scattering using the FDTD method is presented. The strut, formed by joining two radome panels, consists of a dielectric rectangular rod and retaining bolts. Tuning using longitudinal wires embedded in the strut is studied and verified experimentally. Comparison between the FDTD and near-field measurements for a scaled strut model shows very good agreement
