his example calculates the impedance of a microstrip line on a printed circuit board. It compares the impedance with that obtained from an analytical formula given the dimensions of the micro strip and permittivity of the circuit board. This formula

通过matlab编程，利用FDTD算法来计算微带带通滤波器的S参数，适合初学者熟悉FDTD算法。我用的板材是Rogers5880板材，厚度为0.508mm(Through MATLAB programming, the use of FDTD algorithm to calculate the S parameters of microstrip bandpass filter, suitable for beginners familiar with FDTD algorithm.)
