) -> cfdfield_t: # TODO DOCS
) -> cfdfield_t:
"""
Given an eigenmode obtained by `solve_mode`, calculates an overlap_e for the
mode orthogonality relation Integrate(((E x H_mode) + (E_mode x H)) dot dn)
[assumes reflection symmetry].
TODO: add reference
TODO: add reference or derivation for compute_overlap_e
Args:
E: E-field of the mode
H: H-field of the mode (advanced by half of a Yee cell from E)
wavenumber: Wavenumber of the mode
omega: Angular frequency of the simulation
dxes: Grid parameters `[dx_e, dx_h]` as described in `meanas.fdmath.types`
axis: Propagation axis (0=x, 1=y, 2=z)
polarity: Propagation direction (+1 for +ve, -1 for -ve)
slices: `epsilon[tuple(slices)]` is used to select the portion of the grid to use
as the waveguide cross-section. slices[axis] should select only one item.
mu: Magnetic permeability (default 1 everywhere)
Returns:
overlap_e such that `numpy.sum(overlap_e * other_e.conj())` computes the overlap integral
