Why are Cell Towers Placed on Hilltops?

I'm sure we all notice it, on top of a hill, one would often see a lone solitary telecommunication tower stand amidst the surrounding vegetation and trees. Although not a must, a telecommunication tower is often built on higher elevations. This is due to the mode in which microwave propagate, which is called Line-of-Sight (LOS) …

5 Minutes Introduction to EM Wave

In the previous article, we mentioned that James Maxwell unified the electric and magnetic fields by combining the four Maxwell’s equations into a single wave equation which predicts the existence of the electromagnetic (EM) wave. The discovery of EM wave is a major breakthrough in modern physics because it let us understand the phenomena of …
