Abstract (en)

A broadband frequency selective delay device is provided in a small configuration. A source antenna (34) transmits the multifrequency signal in the direction of several frequency selective surfaces (38, 40, 42). Each of the frequency selective surfaces (38, 40, 42) redirects a different frequency component of the signal to a receive antenna (46) that combines the redirected signal components to produce a compressed signal or a stretched signal, depending on the way in which the frequency selective devices are arranged.
