The propagation of sound in wet close granular media can excite two expand waves and a rotationwave.
声波在其中传播时将出现两个膨胀波和一个旋转波。

One part is not effected by Faraday rotation, because of cancellation of rotating angels for two oppositing polarized waves, so it is called as ordinary wave.
波场仍分为两部分，一部分，因法拉第旋转角相互抵消，而不受影响，即寻常波。

But the so-called extension wave stove is lets the microwave radiation in the furnace chamber internal rotation, is more advantageous in the heating is even.
