Spectral Element Method for the Elastic/Acoustic Waveguide Problem in Anisotropic Metamaterials
An Qi Ge, Ming Wei Zhuang, Jie Liu +1
In order to simulate elastic wave propagation in a complex structure with inhomogeneous media, we often need to obtain the propagating eigenmodes of an elastic waveguide. As the wa…

Mixed Spectral Element Method for the Waveguide Problem with Bloch Periodic Boundary
Jie Liu, Wei Jiang, Na Liu +1
The mixed spectral element method (MSEM) is applied to solve the waveguide problem with Bloch periodic boundary condition (BPBC). Based on the BPBC for the original Helmholtz equat…
