Modified A* Pathfinding Algorithm for Grid

Lets say you want to travel from point A to point B and you are given 3 options. Option A is a straight path but with many obstacles, option B is longer but with fewer obstacles and Option C is the longest path but with no obstacles. How would you determine which path will get …

Single and Dual Mode Resonator

What is a resonator? In simple words, it is any circuit that produces a resonance at a particular frequency. A resonance frequency is when a frequency is exhibiting greater amplitude when compared to other frequencies. In some applications, resonance frequencies are undesirable as it could mean an anomaly in the response graph. For example in …

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) …
