Short Electromagnetic Waves of Wave-length up to 82 Microns

UP to the present date, short electromagnetic waves have been generated only by the method of the Hertz vibrator. This method offers very serious difficulties when we try to produce electromagnetic waves of the smallest possible length, as the vibrator burns out very soon, so that the amount of the energy and the length of the waves produced do not remain constant, and also as the length of the waves decreases slowly, if the dimensions of the vibrator are diminished, when we approach the region of the very shortest waves. The experiments of many investigators who have tried to fill the interval between the short electromagnetic waves of Lebedew and the long heat-waves of Rubens, have proved how difficult it is to obtain the shortest electromagnetic waves by the Hertz method, and have shown the necessity of finding a new method.
