10.11. DXF at XZ frame

DXF can be loaded in XZ frame. This can be performed in different ways:

1. Loading data from x, z parameters

2. Loading data from a variable

3. Loading size from the .dxf file

In the 2. and 3. cases, number of pixels are required.

10.11.1. Modules

from diffractio import np, plt
from diffractio import um, mm, degrees

from diffractio.scalar_masks_XZ import Scalar_mask_XZ
from diffractio.scalar_sources_X import Scalar_source_X

10.11.2. Loading data from x, z parameters

x = np.linspace(-.150*mm, .150*mm, 256)
z = np.linspace(0*mm, 1*mm, 512)
wavelength = 5*um

filename_dxf = './hatch_polyline2.dxf'

u0 = Scalar_source_X(x=x, wavelength=wavelength)
u0.plane_wave()

t0 = Scalar_mask_XZ(x,z,wavelength)
t0.dxf(filename_dxf, n_max=2, n_min=1, invert=False, verbose=False)
t0.draw_refractive_index(scale='scaled', colorbar_kind='horizontal')

10.11.3. Loading data from a variable

t0 = Scalar_mask_XZ(x=None, z=None, wavelength=wavelength)
t0.dxf(filename_dxf, n_max=2, n_min=1,  num_pixels=(512, 256),
       extent=[-500*um, 500*um, 0, 2000*um], units='um', invert=False, verbose=False)
t0.draw_refractive_index(scale='scaled', colorbar_kind='vertical')

10.11.4. Loading data from .dxf size

t0 = Scalar_mask_XZ(x=None, z=None, wavelength=wavelength)
t0.dxf(filename_dxf, n_max=2.5, n_min=1,  num_pixels=(512, 256),
       units='um', invert=False, verbose=False)
t0.draw_refractive_index(scale='scaled', colorbar_kind='vertical')
