Abstract

O EFEITO MULTIPACTOR ENCONTRA-SE ENTRE OS PROBLEMAS MAIS NOCIVOS QUE PODEM OCORRER EM CAVIDADES RESSONANTES E GUIAS DE ONDAS, NOMEADAMENTE EM SISTEMAS DE TELECOMUNICAÇÕES PARA APLICAÇÕES ESPACIAIS. EM DETERMINADAS CONDIÇÕES, EMISSÃO EM CASCATA DE ELECTRÕES SECUNDÁRIOS EM RESSONÂNCIA COM O CAMPO ELECTROMAGNÉTICO QUE PERMEIA A CAVIDADE DEGRADA O DESEMPENHO DESTA, COMPROMETENDO A SUA FUNCIONALIDADE. O MÉTODO PROPOSTO, QUE CONSISTE NO ENCHIMENTO DA CAVIDADE COM AEROGEL DE BAIXAS PERDAS DIELÉCTRICAS, REDUZ DRASTICAMENTE O FENÓMENO MULTIPACTOR E AUMENTA A LONGEVIDADE DO DISPOSITIVO. O AEROGEL PODE TER UMA TEXTURA MONOLÍTICA, EM GRÃO, PÓ OU ESPUMA.
