Proposal for a New Æther Drift Experiment

Abstract

ALTHOUGH all experiments of the type of the Michelson experiment (with the exception of Miller's experiment) have shown that the second-order effects predicted by classical (non-relativistic) optics as results of an ‘æther drift’ do not exist, no experiments seem to have been carried out for testing whether such second-order effects could not be detected with standing electromagnetic waves. In view of the fact that the frequencies of microwaves in the centimetre region can now be measured with extraordinary accuracy, such waves could be used for this purpose with great advantage.
