Question

How to Calculate the total scattered radiation power and total radiation power.?

Answer 1

Let's suppose I have incident field EizEzi.
The components of Scattered electric and magnetic field are EszEzs, EsϕEϕs, HszHzs and HsϕHϕs.
The electric and magnetic field components transmitted into scattered objects are EtzEzt, EtϕEϕt, HtzHztand HtϕHϕt.I don't know whether its correct or not but I used Ps=|z0ES|2Ps=|z0ES|2 to calculate the total scattered radiation power where Es=Esz+EsϕEs=Ezs+Eϕsand z0z0 is impedance in free space.Now I want to know whether my formula for scattered radiation power is correct.? Further I want to know how can I calculate the total radiation power

Answer 2

the all the three down mentioned formula should be used:-

◆ Ps=|z0ES|2Ps=|z0ES|2 

◆EszEzs, EsϕEϕs, HszHzs and HsϕHϕs.

◆ Es=Esz+EsϕEs=Ezs+Eϕs
