Tan Delta : How to use it in lossy material

[Rf engineer]

Hello,

I have plotted a scattered field from a dielectric cylinder, assuming it lossless.....

now I have to plot it assuming it lossy, I am given with only one parameter, tan delta = 0.01.

Can some one guide me how to place this tan delta in calculation expressions..... for example I have some expression like

E(x,y) = (epsilon_r - 1).H(Bp)......etc etc...... so how can i modify this equation to incur tan delta.....


thanks

hi
i think you should multiply all terms in exp(tan delta)
