Abstract
Description
本発明の実施形態の更なる態様に従って、図1の材料評価システムを用いる方法は、EM波伝搬の原理に基づく。コンピュータベースのプロセッサ22は、調整可能なRF信号源を制御し、そのRF信号源は、耐火材料を十分に低い損失で適切に通過する周波数帯域で稼働するものであり、その周波数帯域は、望ましくは0.25GHzと30GHzとの間のどこか、より望ましくは0.25GHzと6GHzとの間のどこかの周波数帯域である。RF信号源は、EM波ランチャ10内部で少なくとも一つの伝搬モードを励起し、複数のEM波が、関心の周波数帯域において供給端12から送出端14へ伝搬することができるように、同軸ケーブル20によって供給推移部18へ伝えられる。EM波ランチャ10内で伝搬するEM波の帯域は、利用者に要求されるように、通常、低くても2GHzが選択される。
本発明は、電磁波の利用を通して、耐火材料などの材料内部の欠陥を検出して測定するためのシステム及び方法に適用可能である。デバイスは、表面検査の分野で産業上製造され実施され得る。
