WebThe lowest frequencies are radio waves. On land, they are produced by antennas: the movement of electrons in the antennas produce these radio waves. Antennas on roofs are the opposite: waves produce electrons’ movements, i.e., … WebThe applicability of surface wave devices to practical electronic systems is basically determined by the centre frequencies, bandwidths and delays obtainable. The upper limit for the centre frequency is determined by fabrication techniques, and current lithography is about 1.5 GHz. At low frequencies SAW devices become more bulky and expensive …
