We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

不一样是理所当然的,因为第一种情况所谓的基底是一个谐振腔,而后一个才是真正的基底,下表面不产生反射。如果想包含下表面对透射率做修正,一个简单的方法是仅用正入射情况做菲涅尔反射损失修正,即将透射率乘以1减菲涅尔反射。更精确的可以用菲涅尔系数按不同角度修正,不过一般没有必要。
