          <datacite:description descriptionType="Other">最近は移動体通信用として、小形集中定数サーキュレータやデュアルバンド化アイソレータのほか、磁性薄膜を用いた静磁波の非直線性を利用した衛星放送受信機用SNエンハンサなどが実用されている。またフェライトの非直線性を用いたソリトン波の性質も研究されている。本稿では歴史的背景をふまえてこれらを述べる。</datacite:description>
          <datacite:description descriptionType="Other">Recently, Microwave ferrite devices are widely used fbr the movable communications and the low noise receiver such as satellite receivers. For example, the miniaturized lumped element circulator with ceramic integrated circuit, dual band circulators, isolators and SN enhancers with magnetostatic waves propagating on thin ferrite plate are the main devices. This paper presents the principles and the performances of the devices especially mentioned above together with the historical background.</datacite:description>
