Resonance transmission through electromagnetic crystals consisting of metal strips

Abstract

In this letter, we present frequency-selective transmission of a 2D (two-dimensionally) electromagnetic (EM) crystal. Such a 2D EM crystal consists of a finite stack of one-dimensionally metal-strip gratings. The rigorous mathematical formulation using the mode-matching method incorporating the Floquet solution was employed to calculate the scattering and guiding characteristics of the structure under consideration. Additionally, the experimental studies were also carried out to verify the numerical results. Significantly, the correlation between frequency-selective transmission and the Fabry-Perot resonance was clarified.ABSTRACT: Demonstrated was a 10 Mbit/s binary frequency shift keying subcarrier multiplexing system operating beyond the pass-band of 1 km MM graded index optical fiber. The system automatically adjusted the carrier frequency to the fiber frequency response. Transmission of four 10 Mbit/s channels was also shown over the same fiber. No visible channel interaction was observed.
