I have a equation for irradiance distribution that says.
it's an radiance distribution where the k is the wave vector , Λ is the period between the emitting elements. Implementing the equaiton can give the plot showing below. I am struggling to implement this equation when I plug everything in all I get is a single value. How do I loop this equation and create a matrix so it can give me the plot that is shown below ?
I_0 = 1;
period = 2e-6;
theta = 20;
I = I_0*abs(((sind(k*period*sind(theta))/k*period*sind(theta))*(sind(numel/2*k*sind(theta))/sind(0.5*k*period*sind(theta)))))
For now I am trying to implement the equation to have the plot like below. But this will only give a signle value. How can I implement the right equation to have the plot shown above.
