Berreman’s matrix method is a common method to study and calculate the optical properties of liquid crystals. In order to reduce the computational complexity, many scholars have devoted themselves to simplifying the method in recent years to improve the computational speed. According to the electromagnetic field theory of light propagation in anisotropic media and the optical folding and reflection The law of matrixes, while guaranteeing its accuracy, introduces a new matrix method, which shows that the 2 × 2 matrix formula is quite simple.Theoretical results show that this method reduces the amount of computation in the past, is quick and concise and accurate
