We show that when a narrow beam is incident upon a dielectric interface near the critical angle for total internal reflection it will be transmitted into the far field with an angular deflection from the direction predicted by Snell's law, because of a phenomenon that we call "Fresnel filtering." This effect can be quite large for the parameter range that is relevant to dielectric microcavity lasers.
我们表明，当一束窄光束以接近全内反射临界角的角度入射到电介质界面时，由于一种我们称为“菲涅耳滤波”的现象，它将以偏离斯涅尔定律预测方向的角偏转被传输到远场。对于与电介质微腔激光器相关的参数范围，这种效应可能相当大。
