legume.Layer

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

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

__init__(lattice, z_min: float = 0, z_max: float = 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_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.
