We report an ingenious yet efficient method to fabricate ordered vertically aligned nitrogen- and sulfur-codoped carbon nanowire (NS-CNW) arrays by direct carbonization of the finely designed ...

Abstract: An array factor approach of leaky-wave (LW) antennas is proposed for efficient and fast computation of the radiation patterns of complex metamaterial LW structures of arbitrary length from ...

The present work focusses upon the realization of the concentric ring sparse array antenna using fractal structures. It demonstrates high sparsity and low SLL features in the resulting designs and ...
