Finite Element Method for Guided Wave Mechanics

The finite element method (FEM), also known as finite element analysis (FEA), is a widely used numerical solution approach for solving problems of wave propagation and vibration. For some complex differential or integral equations without analytical solutions, FEM can provide accurate and computationally efficient solutions that may be improved by refining the elements used in the study. FEM may be combined with analytical analysis or other numerical methods to achieve optimum solutions.
