Data comms beyond light speed
Research papers by their nature are difficult for the average layman to understand. Here in the Elektor Electronics laboratory between the odd cup of coffee we spend much time studying scientific reports. A recent paper by a Japanese research group caught our eye because we were able to replicate the effects described using a very simple circuit and the results are so profound that it could change forever the way we send data.The properties of light that most of you will be familiar with are that it travels in a straight line at a speed, c, of approximately 3 x 108 m/s. We should not forget to mention that this is only true when it is passing through a vacuum and not influenced by gravity. As soon as it enters another medium, light is slowed down and bent (refracted).
