Radiation Intensity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radiation Intensity = Isotropic Radiation Intensity*Directivity of Antenna
U = U_o*D_a
This formula uses 3 Variables

Variables Used

Radiation Intensity - (Measured in Watt per Steradian) - Radiation Intensity refers to the power radiated per unit solid angle by an antenna in a specific direction.
Isotropic Radiation Intensity - (Measured in Watt per Steradian) - Isotropic Radiation Intensity refers to the radiation intensity of an idealized isotropic radiator.
Directivity of Antenna - Directivity of antenna measures the degree to which the radiation emitted is concentrated in a single direction.

STEP 1: Convert Input(s) to Base Unit

Isotropic Radiation Intensity: 0.09 Watt per Steradian --> 0.09 Watt per Steradian No Conversion Required
Directivity of Antenna: 0.08 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

U = U_o*D_a --> 0.09*0.08

Evaluating ... ...

U = 0.0072

STEP 3: Convert Result to Output's Unit

0.0072 Watt per Steradian --> No Conversion Required

FINAL ANSWER

0.0072 Watt per Steradian <-- Radiation Intensity
