Plasmons are collective oscillations of the free electron gas density, for example, at optical frequencies (.) Since plasmons are the quantization of classical plasma oscillations, most of their properties can be derived directly from Maxwell's equations.Р”В¬ST COMPUTER SIMULATION TECHNOLOGY | What is a Plasmon? Therefore, the metamaterial lens horn structure results in a miniaturized antenna design approach compared to the optimum conventional horn of the same aperture size and gain in the interested frequency band.CST COMPUTER SIMULATION TECHNOLOGY | Optical Applications with CST Microwave StudioР”В¬ST COMPUTER SIMULATION TECHNOLOGY | All solvers solve Maxwells EquationsQuantum effects are not considered, so: The results show that the gain of a wide flare angle horn antenna is enhanced with over 2 dB between 16.10 17.30 GHz after the metamaterial is utilized. For the characterization of the antenna, the electric-field distribution in radiation area, reflection parameter (S 11), gain and radiation pattern are calculated. In this structure, a periodic-structure metamaterial with three-layer metal grids is designed using the CST Microwave Studio for optimization and its zero refraction property is validated. Unlike conventional curve lenses, the lens is designed in the present work using a fully flat structure, which results in a great improvement for the directivity of the horn antenna based on the zero refraction characteristics of the metamaterial. In this paper, a horn antenna filled with a metamaterial structure as lens inner the aperture is presented.
