Antenas de bocina optimizadas para acoplar modos gaussianos de orden superior

Abstract

The concept of higher order free space modes, gaussian-like beam modes can be applied to efficiently transport the power generated by a gyrotron for technological applications. Waveguide modes can be coupled properly to higher order gaussian modes. These modes can be guided by an optimized higher order beam waveguide to the final experiment. A family of optimized non linear horn antennas is investigated in order to maximize the coupling between the guided output modes of a technological gyrotron and the free space modes. The numerical computations show very favourable coupling to higher order gaussian modes, with a conversion effiencies of about 99.8%.
