TMM

Installation

Just download the whole package and run $ python example.py

How to use

1. First, make a TMM object.

   import TMM
   example = TMM.TMM()

2. Set the range of wavelength.

   wl = np.arange(550,750,0.2) * nm
   example.set_wavelength(wl)

3. Then, set the incident angle. Only the incident angle is considered in this short script. Azimuthal angle is not tunable.

   To set an incident angle,

   example.set_incidentangle(angle=np.pi/6, unit='radian')

4. Set the material properties of the medium. If the medium consists of 4 layers, put six arguments. The first and last arguments are the medium indices for the input(incident) field and output(transmitted) field. If the 4 layers are placed in a vacuum or air, the first and last argument should be 1. The thickness of the mediums can be set by the set_mediumthick method. It also takes 4 arguments because the thickness of the input and output medium is not considered in TMM.

   example.set_mediumindex(1, 1.2, 1.1, 2.2, 1.4, 1)
   example.set_mediumtype('nonmagnetic')
   example.set_mediumthick(800*nm, 502.4*nm, 753.6*nm, 402.4*nm)
