ABSTRACT:
A method for measuring properties of an electromagnetic signal includes following steps. An electromagnetic signal measuring device that includes a carbon nanotube structure is provided. The carbon nanotube structure has a plurality of carbon nanotubes. An electromagnetic signal is received by the carbon nanotube structure in the electromagnetic signal measuring device. The intensity of the electromagnetic signal is measured by a sound produced by the carbon nanotube structure.
