range of the radio (a)

[jnecochea]

Hello everyone

I have a problema with Sz1 (i need to use 0 < r < a)

and Sz2 (i need to use a <= r < infinite)

I need to graph both Sz1 and Sz2 in the same plot

I upload the file poynting.mcdx

thank you for your help

You need to fix the units. The index n is confusing,  should it be dimensionless? The measurement units of the Poynting vector are Watt on square meter. When the units are OK then you can try to plot graphs.

Here below there is my attempt to correct the units. But the units of the Poynting vectors are not correct.
