Estudio de la posibilidad de utilizar modos de orden superior en guías de onda cuasi-ópticas

Trabajo presentado al X Simposium de la Unión Científica Internacional de Radio (URSI'95). Valladolid, septiembre de 1995.The possibility to employ low power gyrotron tubes (10-30 kW, CW) at millimeter wave frequencies (30-100 GHz) has potential applications in advanced ceramic sintering, surface coating, radar, remote sensing, etc.. In materials processing applications, the final shape of the beam is not relevant, because the experiment have to be done in a cavity which has a metallic mode stirrer in order to obtain inside a uniform distribution of the electromagnetic fields. In this paper, we present a preliminar study, showing that it is possible to use high order modes in the transmission line to carry the power to the final experiment efficiently.Este trabajo ha sido financiado por el MEC y el BMBF dentro del programa Acciónes Integradas Hispano Alemanas 1995
