When simulating the case (“Diffuse Scattering Film for Automotive Display”) in the case base, I found that some of the script commands as as follows. What is the meaning of ” norm_calc = exp( -(Theta\/beam_width)^2 ); “<\/p>\n
norm_calc = exp( -(Theta\/beam_width)^2 ); # Where Theta_out is the matrix of reflection angles,and Theta = meshgridx(theta_out,phi_out); beam_width=2<\/p>\n
beam_norm = integrate(norm_calc*sin(Theta*pi\/180),1:2,theta_out*pi\/180,phi_out*pi\/180);<\/p>\n
beam_norm = 1\/beam_norm;<\/p>\n
BTDF(fc,1,1,:,:) = pinch(BTDF(fc,1,1,:,:)) + beam_norm*Ttotal(fc)*order_T(n,m,fc)*exp( -(ThetaDiff\/beam_width)^2 );<\/p>\n
The complete code is as follows:<\/p>\n
