ABSTRACT:
Disclosed herein is a pyramid-shaped near field probe which forms and changes a near field at the aperture of the probe. The pyramid-shaped near field probe of the present invention includes a probe body and metal films. The probe body is constructed in the form of a pyramid using a semiconductor process using a dielectric member and receives an electromagnetic wave. The metal films are symmetrically coated on two predetermined sides of four sides of the probe body while being spaced apart from each other. The pyramid-shaped near field probe allows a surface plasmon wave induced on the surfaces of the metal films due to the electromagnetic wave to progress to the aperture of the probe body through the boundary surface between the probe body and the metal films.
