The number of entries is equal to the number of layers. Specifies the step size of the real part of the permittivity. As the GA code encodes the parameters in binary we need a step size for encoding. This means that the value of the real part of the permittivity for any layer in the sample input file lies between 1.03 and 12.0 and will be incremented by 0.01. The next three entries correspond to the y-directed periodicity.
All dimensions are in centimeters.
Specifies the minimum, maximum and the step-size for the surface resistance of a FSS screen with finite conductivity. The first, second, and third entry correspond to the maximum thickness, the minimum thickness and the size of the increment for the thickness of a single layer in the composite. This is used when the GA program needs to be restarted from the generation number it last ended with. For example, the first 100 generations are run using 0 for no restart. Then the program terminates and gives you a set of results.
