An international team of researchers (Austria, France) has developed a method that allows the calculation of a tailor-made anti-reflective structure which can be used to design an additional layer to the medium only partially permeable to a wireless signal so that the entire signal can be channeled through the medium without reflections. To determine the anti-reflective structure they sent the waves through the medium and measured exactly in which way these waves are reflected by the material. Using a mathematical technique they calculated the corresponding compensating structure so that the combination of both media allowed the waves to pass through without distortion. According to the researchers their invention could be useful for better wireless reception, imaging techniques, the next generation of mobile communications allowing the reduction of signal intensity…read more.
