Abstract: A novel strategy for the design and optimization of large-scan phased arrays is proposed. Active electronic beam-scanning antennas offer an unparalleled set of degrees of freedom, but they ...

Abstract: A new decoupling scheme named three-port coupled resonator decoupling network (CRDN) is proposed. The matching and decoupling conditions for the three coupled antennas are proposed, and the ...

Im2mesh is an open-source MATLAB/Octave package for generating finite element mesh based on 2D segmented multi-phase image. It provides a robust workflow capable of processing various input images, ...
