Hello all.
I'm working on FDTD + CPML and for now my objective is to plot the power delay profile or for other words a graph with time in order of power.
I′m using TEz mode.
The manner that I′m calculating the power in dBW is:
10log(((Ex^2+Ey^2)*lambda^2*1)/(120*pi*4*pi))
where I admite that I′m using an isotropic antenna with unitary gain.
Comparing with a paper that I have, I′m confused because the result is similar but the value of power is bigger, in order of aproximately 50dB (1e6 Watt peak :( ) that is impossible in practice.
Someone can please help me?
Thanks a lot.
