Group velocities below 71,000 km/s on one hand, well exceeding the speed of light in vacuum on the other hand and even negative group velocities can readily be obtained. %K Flexible control %K Negative group velocities %K Ciencias tecnológicas %K Electrónica %K Technology %K Electronics %~ Biblioteca Universidad de Alcala
