13.layer

Description:
  Focused beam, wavelength 650nm,
  incident from air on the flat 50nm aluminum layer coated over
  a glass substrate.

  Structure, top to bottom:
     layer1   n=1.0 
     layer2   50nm Al, n+ik=2+7i
     layer3   n=1.5
  distance from Al top to R plane=180nm
  Lx,y=12*lambda=7800nm
