Considering the greater amounts of energy which can be collected and stored in suitable experimental form in capacitors, one could expect to deliver radiated energy for some time from them.
Karl Ferdinand Braun
Elementary considerations led me to the conclusion that a medium, composed of layers of different dielectric constants, must behave as a uniaxial crystal if it is assumed that the layer thicknesses are only a fraction of a wave-length.
In the summer of 1902, I was able to erect two experimental stations on two forts at Strasbourg for the purpose of closer study.
