Abstract

Предложена регулируемая катушка индуктивности, включающая первый и второй коаксиальные и концентрические трубчатые элементы, содержащие анизотропный материал, соединенные друг с другом у обоих торцов магнитными торцевыми соединительными элементами; первую спиральную обмотку вокруг обоих магнитных трубчатых элементов и вторую спиральную обмотку вокруг по меньшей мере одного магнитного трубчатого элемента, где ось первой спиральной обмотки перпендикулярна оси по меньшей мере одного магнитного трубчатого элемента, а ось второй спиральной обмотки совпадает с этой осью, причем первая обмотка выполнена с возможностью генерации магнитного поля в первом направлении, которое совпадает с направлением первой магнитной проницаемости, а вторая обмотка выполнена с возможностью генерации магнитного поля во втором направлении, которое совпадает с направлением второй магнитной проницаемости, и первая магнитная проницаемость существенно выше второй магнитной проницаемости.
