Hello, I have this equation that computes the electric field from electric currents. E=-j*k_n (J*C_1- (J*R|R*C_2) e^ -j*k*R/4πR ) The data are: k_n=377 , k=20.93 , R=Sqrt(3) ,J_x=0.72576821 ,J_y=0.03763659 , J_z=0.86104220 , C_1=0.999239077741 + 1 / 36.2518234024j C_2=0.997717233223+ 3 / 36.25182344024j R_x=R_y=R_z=0.57735026919 I have 3 questions. 1) From the above equation i must compute E_x ,E_y,E_z. When i compute E_x i will compute J_x*C_1 - (J*R|R*C_2) ? And specific: I will compute the J*R dot product as : J*R=J_x*R_x+J_y*R_y+J_z*R_z ? Or only the J*R=J_x*R_x ? 2) The computation J*R|R*C_2 . How will i do the computation for the symbol ' | ' ? I will compute the dot product , then the R_x*C_2 and then what?How to compute the whole J*R|R*C_2 ? 3) How to deal with the C_1 and C_2? I mean they have the imaginary part in the denominator.What is the best approach? Thank you!
