Having problems with the imaginary (j). Side note, eqns below are related to electric and magnetic fields. Em = constant j = imaginary B = beta z = distance z phasor form: k*sin(pheta)/(2*pi*epsilon)*e^(-j*B*r)*j*w/(c^2*r) convert into real time form k = constant pheta = angle epsilon = constant B = beta r = distance r w = omega c = constant

Masadi is correct that your equation is not clear! Another thing: e^(-j*B*r)*j*w = e^(B*r*w) = not imaginary!
