How to Calculate Power that Crosses Surface of Sphere?
Power that Crosses Surface of Sphere calculator uses Power Crossed at Sphere Surface = pi*((Amplitude of Oscillating Current*Wavenumber*Short Antenna Length)/(4*pi))^2*Intrinsic Impedance of Medium*(int(sin(Theta)^3*x,x,0,pi)) to calculate the Power Crossed at Sphere Surface, The Power that Crosses Surface of Sphere formula relates the time-averaged power density to the time-average Poynting vector across the surface of a sphere with radius r centered at the antenna. Power Crossed at Sphere Surface is denoted by P_{sphere} symbol.
How to calculate Power that Crosses Surface of Sphere using this online calculator? To use this online calculator for Power that Crosses Surface of Sphere, enter Amplitude of Oscillating Current (I_{o}), Wavenumber (k), Short Antenna Length (L), Intrinsic Impedance of Medium (η_{hwd}) & Theta (θ_{em}) and hit the calculate button. Here is how the Power that Crosses Surface of Sphere calculation can be explained with given input values -> 39371.69 = pi*((5*5*3.69)/(4*pi))^2*377*(int(sin(0.5235987755982)^3*x,x,0,pi)).
