The term "line-of-sight" typically refers to the obstacle presented by the curvature of the Earth or large metallic objects[1]. An insect would not block a THz EM wave, just as the walls of your home (probably) don't block your cell phone's radio. [1] http://en.wikipedia.org/wiki/Line-of-sight_propagation |
