Разработан алгоритм определения диэлектрической проницаемости. Приведены результаты измерений амплитуды и фазы коэффициента отражения  и коэффициента передачи для текстолита и воды. Получена зависимость диэлектрической проницаемости текстолита от частоты в диапазоне 78,33–105,0 ГГц.</p></abstract><trans-abstract xml:lang="en"><p>Modified free space method using a vector network analyzer is proposed.
