Refractive index of wood
WebJun 23, 2009 · The index of refraction (= sqrt (dielectric constant)) in materials is a complex number, meaning that it has both refraction properties (like glass) and attenuation properties (like opaqueness). It is the attenuation property that reduces the transmission of microwaves.
