Abstract
EL DIFUSOR ESTA REALIZADO A PARTIR DE N=2N CONDUCTOS LUMINOSOS QUE CONSTITUYEN DOS CONJUNTOS DE N/2 CONDUCTOS CADA UNO A RAZON DE UN CONDUCTO SOBRE DOS. LOS CONJUNTOS SE ENROLLAN HELICOIDALMENTE, EN SENTIDO CONTRARIO, CON EL MISMO PASO DE HELICE, SOBRE UN CILINDRO (1). CADA CONDUCTO DE UN CONPUESTO CRUZA LOS N/2 CONDUCTOS DEL OTRO CONJUNTO Y LOS APAREADORES SE REALIZAN POR CRUZAMIENTO DE NUMEROS 2Q, Q=0,1,2,...,(N-1), DE UN CONDUCTO CON LOS N/2 CONDUCTOS DEL OTRO CONJUNTO. EL DIFUSOR CONSTA DE PISOS DE N/2 APAREADORES CADA UNO, CADA PISO ESTA DISPUESTO SEGUN UNA CORONA DEL CILINDRO.
