Abstract
A new approach to controlling the flow of a plasmatic electron packet at the interface between metallic and dielectric layers is described. The proposed metamaterial structure operates in the optical frequency range and can be used as a digital processing filter. It exhibits two double negative resonances and one special passband region, while the existence of a metal-dielectric nano-tunnel enhances electromagnetic wave-metal interactions. The structural arrangement of this metamaterial coupled with the tunnel layer can effectively control the electric field and allows digital encoding of electron packets.

A new approach to controlling the flow of a plasmatic electron packet at the interface between metallic and dielectric layers is described
Metamaterials strongly affect the propagation of electromagnetic waves due to their special structural arrangements that cannot be found in nature
Giovampaola and Engheta[11] utilised digital metamaterials consisting of negative metal and positive dielectric layers for manufacturing lens and tunnelling applications operated at optical frequencies to create metamaterial bits
Summary
Eistiak Ahamed[1], Mohammad Rashed Iqbal Faruque 1*, Md. Jubaer Alam[1], Mohd Fais Bin Mansor 2 & Mohammad Tariqul Islam[2]. The proposed array pattern consists of five-unit cells; the dielectric and metal parts create eleven intense electron clouds. These parts react with a propagating electromagnetic wave as shown in the figure. The propagating electromagnetic wave is incident on the first metamaterial array, and the modulated electron clouds are divided segment wise These clouds are converted by the insertion of the tunnel (Fig. 6) that can be explained digitally.
