1. According to the values of LP01 modulus V and W, the linear relationship between V and W in [1.5, 2.4] of the fitting example is fitted, and the maximum error of the fitting is given. (hint: use the function polyfit(), polycal())
2. The concept and significance of three transmission constants u, V, W and degenerate modules are explained.
3. Combined with the simulation results (including the simulation results in the example), the influence of u, V and w on the guided wave is described.
Tip: mode cutoff, mode away from cutoff, etc
