При разработке усилителей сверхвысоких частот (СВЧ) большой и средней мощности, широко используемых в радиоэлектронном приборостроении, применяются цельнометаллические резонаторные замедляющие системы (ЗС), обеспечивающие необходимый теплоотвод. Эти ЗС являются трехмерными, а моделирование приборов, создаваемых на их основе с использованием строгих электродинамических программ, требует больших затрат вычислительных ресурсов. Поэтому разработка простых и точных моделей резонаторных ЗС, используемых при ...
