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…

Doubly Enhanced Third Harmonic Generation in Metal-Based Silicon Nanodisks
Jin Yao, Na Liu, Guoxiong Cai +1
Doubly enhanced third harmonic generation (THG) is realized by the electric dipole resonance (EDR) in silicon nanodisks placed onto a metallic film at near-infrared. By introducing…

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…
