//Chapter 4: Radiation
//Example 4-5.1
clc;
//Variable Initialization
dl = 1e-2 //Length of radiating element (m)
I_eff = 0.5 //Effective current (A)
f = 3e9 //Frequency (Hz)
c = 3e8 //Velocity of light (m/s)
//Calculation
w = 2*%pi*f //Angular Frequency (rad/s)
P = 20*(w**2)*(I_eff**2)*(dl**2)/(c**2) //Radiated power (W)
//Result
mprintf("The radiated power is %.2f W", P)
//The answer obtained is varying compared with the textbook answer because of a calculation error
