A wave front from an omnidirectional goes in all directions, a wave can be directed as in a wave guide. If you had studied electromagnetic wave propagation in a rectangular waveguide, you would have heard of such terms as phase velocity and group velocity of the wave. That is how it is described, in the standard literature. Now that would be too much for einstieinians and their fools to grasp, of course. Obviously, a line of sight situation between transmission and reception is as a guided wave, only with much more losses because the wave is not guided. The reflections, refractions involved in wave interactions with matter, can only be analysed with wave velocity components. Cheers, Arindam Banerjee

The fact that einsteinians still exist, and have mastered the art of talking gobbledygook to impress stupid politicians to extract public moneys, is the single greatest reason for absence of any fundamental new reserarch in the modern world. Stupidity abounds, when the clever of the population turn to making quick money as doctors, lawyers, managers, CEOs, sportspersons, mediapersons, etc. Ah well, this is probably the cyclical nature of things! Let us hope that my ideas relating to the Internal Force Engine and the Hydrogen Transmission Network finally make it to the public mind (today I am comprehensively outcasted) before the planet turns into something like Venus, with unchecked greenhouse effect going on apace! The more the ruling morons say they are keen to stop it, the more they actually do for the opposite. See how much pollution Al Gore is causing by flying, so much jet engine pollution to thicken the layers causing the greenhouse effect! Parasites all, lamenting the grief they cause to their host!
