Abstract :
It was shown by moment method analysis that soft and hard metamaterial horns offer broadband performance if a metamaterial with the required dispersion can be implemented. It was also shown that the required dispersion curve is monotonically increasing similar to the Drude dispersion, strongly indicating that these horns can be realized. In two accompanying papers the design and analysis of a hexagonal hard metamaterial horn for a multi-beam reflector antenna is presented [8, 9].
