Design of the metasurface based on solid-state plasma for beam scanning
-
摘要: 为了实现空间中波束的动态扫描，设计了一款基于固态等离子体的超表面。采用阵列单元相位曲线拼接的技术，通过拼接介质基板厚度不同的阵列单元的相位曲线来实现0°~360°的相位补偿，并用数值插值的方式建立超表面参变量与相位补偿角之间的映射。结果表明，超表面的反射主波束方向θ分别为15°，25°和30°，计算结果与设计相符合，通过改变固态等离子体的激励区域来重构阵列单元，实现了空间中波束在θ为15°，25°和30°时的动态扫描。此反射型超表面阵列单元的普适性设计方法，降低了阵列单元的设计难度，并通过固态等离子体的可调谐特性实现了空间波束扫描超表面的设计。Abstract: In order to realize dynamic scanning of beam in space, matasurface based solid plasma was designed. Phase compensation of 0°~360° was realized by splicing phase curve of array element of dielectric substrate with different thickness. The mapping between matasurface parameter and phase compensation angle was established by numerical interpolation. The results show that the reflecting main beam direction of the metasurface is θ=15°, θ=25° and θ=30° respectively. The calculated results are in agreement with the designed results. Array elements are reconstructed by changing the excitation region of solid plasma, and dynamic scanning of the beam in the space is achieved in the space of θ=15°, θ=25° and θ=30°. The universal design method of reflective matasurface array unit reduces the design difficulty of array unit, and realizes the design of space beam scanning matasurface by the tunable characteristic of solid plasma.
