Abstract:
There is a need for a detection device which has high photoreceptive sensitivity in a generally wide frequency region including the infrared region. Therefore, in the present invention, by utilizing a phenomenon in which electric field strength is enhanced by surface plasmon resonance in a negative dielectric constant medium, a detection device is provided which has an electromagnetic wave detection portion disposed at a position where the electric field strength is large.
