The Complex to Real-Imag block outputs the real and/or imaginary part of the input signal, depending on the setting of the Output parameter. The real outputs are of the same data type as the complex input. The input can be an array (vector or matrix) of complex signals, in which case the output signals are arrays of the same dimensions.

The wavelength, λ, is related to the wavelength in a vacuum, λ 0, by: λ = λ 0 n. and substituting for λ gives: k = 2 π n λ 0. Now we take our plane wave equation (1) and substitute for k. If we write n as the complex refractive index, n + i ...

WebComplex Numbers are the combination of real numbers and imaginary numbers in the form of p+qi where p and q are the real numbers and i is the imaginary number.
