LOW LATENCY WAVELENGTH-DIVISION MULTIPLEXING SYSTEM COUPLED WITH A SHORT RANGE SURFACE PLASMON POLARITON WAVEGUIDE.

摘要

A low latency wavelength-division multiplexing system coupled with a short range surface plasmon polariton waveguide, comprising: a metal substrate, which has atop surface; a hollow metallic block periodic structure, wherein the hollow metallic block periodic structure is operable in a predetermined working frequency band and defines a forbidden band regime; the hollow metallic block periodic structure comprising a plurality of unit cell blocks that is spaced from each other by a predetermined interval, the unit cell blocks being arranged at a sub-wavelength period in a one-dimensional line-up direction to line up on the top surface of the metal substrate, each of the unit cell blocks generating an electromagnetic field distribution in the working frequency band; a low frequency spoof surface plasmon polariton transmission mode being introduced in the forbidden band regime of the hollow metallic block periodic structure; wherein each of the unit cell blocks comprises a channel space; and under the low frequency spoof surface plasmon polariton transmission mode, the hollow metallic block periodic structure provides a structure of an antenna, the electromagnetic field distribution of each of the unit cell blocks being mostly confined in a channel space of the unit cell block; each of the unit cell blocks comprises: a body; a penetration section, which penetrates through the body by extending in a horizontal penetration direction so as to define the channel space in the body, the channel space being delimited by a left section, a right section opposite to the left section, and a horizontal top section between the left section and the right section; and an open slot, which is formed in the horizontal top section by extending in the horizontal penetration direction so as to divide the horizontal top section into a left top section and a right top section.
