| 20090261919 | MILLIMETER WAVE BAND NONRECIPROCAL DEVICE - [Problem] When a nonreciprocal device operating at 100 GHz to 300 GHz is to be realized by using a conventional magnetic material of garnet-type ferrite or spinel-type ferrite, a huge permanent magnet is required and, therefore, it is very difficult to achieve a millimeter-wave band nonreciprocal device for practical use. | 10-22-2009 |
