EM Waves and the Reflectivity Process

  • Eugene F. Knott


Everyone is familiar with waves in one form or another. A very common example is the way waves propagate over the quiet surface of a pond when a stone is thrown into the water. Concentric rings expand away from the center of the disturbance, becoming weaker the farther they travel. The wave on the surface of the water is a transverse wave, signifying that the actual motion of the water particles (up and down in this case) is at right angles to the direction of propagation. EM waves are also transverse, although no particle motion may be involved. Instead, it is the intensities of the electric and magnetic field strengths that vary in planes transverse to the direction of propagation.1
