The index n is confusing,&nbsp; should it be dimensionless? The measurement <SPAN style="font-size: 13.3333px;"> </SPAN><SPAN style="font-size: 13.3333px;">units </SPAN><SPAN style="font-size: 10pt;">of the Poynting vector are Watt on square meter. When the units are OK then you can try to plot graphs.</SPAN></P><P>Here below there is my attempt to correct the units. But the units of the Poynting vectors are not correct.</P><P><IMG __jive_id="107528" alt="poynting0.jpg" class="jive-image image-1" src="https://community.ptc.com/legacyfs/online/107528_poynting0.jpg" style="height: 1260px; width: 620px;" /></P></BODY></HTML> Mon, 10 Oct 2016 09:20:38 GMT https://community.ptc.com/t5/Mathcad/range-of-the-radio-a/m-p/3938#M1538 -MFra- 2016-10-10T09:20:38Z
