Abstract

The present invention provides an electromagnetic wave transmission waveguide, comprising: a transmission line, a first electric field mode conversion element and a second electric field mode conversion element, wherein the first electric field mode conversion element and the second electric field mode conversion element are respectively arranged on the transmission line Both ends of the first electric field mode conversion element are provided with a first waveguide port element, one end of the second electric field mode conversion element is provided with a second waveguide port element, and the width of the transmission line is smaller than the width of the transmission line. high. The electromagnetic wave transmission waveguide provided by the invention is used to at least solve the technical problem that the electromagnetic wave transmission waveguide cannot be bent, and is applied in the near-field detection.

Description

technical field [0001] The present invention relates to the technical field of waveguides, in particular to an electromagnetic wave transmission waveguide. Background technique [0002] Surface plasmon polariton (SPP) is an electromagnetic field propagating along the interface of metal and medium, which is used to transmit light energy and is not limited by the diffraction limit. The field energy is confined to a region whose spatial dimensions are much smaller than its free-space wavelength, and its properties can vary with the structure of the metal surface. Waveguides are microwave devices used to directionally guide electromagnetic waves at microwave frequencies. Waveguides are widely used in detection, guidance, reconnaissance, communications and other fields. [0003] Existing electromagnetic wave transmission waveguides operating in the millimeter wave and terahertz frequency bands are basically metal waveguides with a rectangular or circular cavity. Due to the limit...
