complex band structure

Please login with a confirmed email address before reporting spam

I am studying complex band structure of a 1D two-layer periodic unit cell consisting of:

One elastic layer One viscoelastic layer (with damping)

My goal is to compute and plot:

Real part of wavenumber (Re(k)) vs frequency Imaginary part of wavenumber (Im(k)) vs frequency

to identify attenuation regions (band gaps).
