An ultra-wideband (UWB) -plane monopulse antenna working in the frequency range from 3.1 to 10.6 GHz is proposed. The UWB -plane two-element array is constructed using Vivaldi antennas. By shortening the adjacent tapered lines of the two Vivaldi antennas and using corrugated edges, sum and difference characteristics of the array are improved. The UWB monopulse comparator is a multilayer planar...
This paper introduces a hybrid SVD-Krylov technique based on the balanced truncation - proper orthogonal decomposition (BT-POD). The method combines the best features of the two categories, namely offers error controls and indicators while preserving the efficiency of Krylov MOR. The most time consuming step related to the POD sampling is embarrassingly parallel, making the method suitable for multi-core...
