一般折射是指遇到水面 玻璃這類材質, 磚瓦水泥牆這種就沒有良好的傳遞效果.
可實際觀察訊號波型, 並非穿透牆面而出, 而幾乎是爬行於牆面, 或是由其他路徑而來.
如果任意相異介質間都可以穿透折射, 那反射是....?   |
一般都是部份反射，部份折射穿透。
有興趣可以看一下下面這篇論文
Propagation Losses Through Common Building Materials
2.4 GHz vs 5 GHz
Reflection and Transmission Losses Through Common Building Materials

截取部份表格
作者在結論也寫到
Reflected energy also shows a strong frequency dependence
that is a function of the thickness of the sample, as
well as its permittivity.
所以反射折射那個比較強，也和牆的厚度有關。
