Following from the previous post above. The user provided me with some assistance however I am still a bit unclear on how to apply the equations provided. Could someone please assist me in determining if the way I calculated the power received from the RFID tag is correct?
Ex = 0, Ey = 0, Ez = 149 (V/m)
Hx = 0.06, Hy = 0.834, Hz = 0 (A/m)
S = E X H = (-124.27 ; 8.94 ; 0)
|S| = 124.59
P = Aperture area x |S| x cos(theta)
P = 0.013539 x 124.59 x cos(38.54) = 1.32W
The aperture area is 0.013539 meters^2.
The angle was calculated using the picture attached. Is this the correct way of calculating the angle?
