legume.Layer

class legume.Layer(lattice, z_min=0, z_max=0)

Class for a single layer in the potentially multi-layer PhC.

__init__(lattice, z_min=0, z_max=0)

Initialize a Layer.

Parameters:

  • lattice (Lattice) – A lattice defining the 2D periodicity.

  • z_min (float, optional) – z-coordinate of the bottom of the layer.

  • z_max (float, optional) – z-coordinate of the top of the layer.

Methods

__init__(lattice[, z_min, z_max])

Initialize a Layer.

compute_exc_ft(gvec)

Compute the 2D Fourier transform of the layer permittivity.

compute_ft(gvec)

Compute the 2D Fourier transform of the layer permittivity.

get_eps(points)

Compute the permittivity of the layer over a 'points' tuple containing a meshgrid in x, y defined by arrays of same shape.
