Ray transfer matrices (also known as ABCD matrices) are one of the most powerful and interesting tools in geometric optics. Mastering them will allow you to easily analyze arbitrary optical systems and discern their properties. These matrices are valid whenever the paraxial approximation holds.
This is part of my series on semiconductor physics (often called Electronics 1 at university). This is based on the book Semiconductor Physics and Devices by Donald Neamen, as well as the EECS 170A/174 courses taught at UC Irvine.
