Special Issue Information
Dear Colleagues,
Metamaterials are subwavelength materials that have dimensions less than one-tenth of an operating wavelength. With their unique features, metamaterials can have extraordinary effects in various applications such as antenna parameter improvement, increasing the sensing capability of sensors, RCS reduction, EM isolation, EM wave manipulation, etc. Symmetric metamaterial unit cells should be designed, because this type of design creates polarization and incident wave independence in an application. For example, symmetric and periodic metamaterial-based microwave absorber structures have the characteristics of polarization or incident wave independence. Furthermore, the geometrically symmetric arrangement of metamaterials can also improve the bandwidths of the applications in general.
In this Special Issue, we present symmetric metamaterial design processes and their advantages and disadvantages. This topic mostly includes microwave and terahertz applications, but the scope of the Special Issue is not limited to these applications. Symmetric metamaterials can also be used various branches of research such as in acoustic, seismic and mechanical applications.

Abstract: In the past century, considerable advancements have been achieved in the domain of multilevel diffractive lenses (MDLs), which are optical devices distinguished by their center-symmetrical structure. One notable example is the widespread use of Fresnel lenses in various optical systems due to their efficiency. Recently, there has been an increased focus on metalenses and their notable advancements. Concurrently, there has been a concurrent development of MDLs, which are propelled by their distinctive attributes including cost-effective production and appropriateness for large-area volume production. In this article, we explore the evolution and underlying mechanisms of MDLs, highlighting the advantages of their central symmetry traits in terms of simulation and optimization time. Furthermore, we conduct a comparative analysis of the performance between MDLs and metalenses, and present a novel fabrication process for MDLs leveraging the rapid advancements in 3D printing technology.
