Defining Calculation Requests

Define the calculation requests in CADFEKO.

This model considers the transmission and reflection coefficients for an incident plane wave.

1. Request a Transmission/reflection coefficients request with the phase origin at (0, 0, 0).
2. Define a 2D periodic boundary condition.
   1. Start point: (-d/2 , -d/2 ,0)
   2. End point of first vector: (d/2 , -d/2 ,0)
   3. End point of second vector: (-d/2 , d/2 ,0)
   4. For Phase shift select Determine from plane-wave excitation.
