Abstract

Patente de Invenção para "DISPOSITIVO PARA INCISãO DE PLASMA DE MATéRIA COM GERADOR DE CAMPO ELETROMAGNéTICO DE RADIOFREQUêNCIA ESPECIFICAMENTE SINTONIZADO". A presente invenção é um dispositivo para aplicar uma incisão em uma matéria (32) com uma nuvem de plasma harmonioso. Um sistema gerador de radiofreq³ência (10) produz uma forma de onda eletromagnética pulsada ou contínua, que é transmitida por uma extremidade do eletrodo de incisão do transmissor ativo (28). Esta onda eletromagnética gerada é utilizada para iniciar uma nuvem de plasma com processos, tais como ionização térmica, e um efeito fotoelétrico que, então, dispara um efeito de avalanche para carregar as partículas atómicas para a superfície da extremidade do eletrodo de incisão do transmissor ativo (28).
