## 1 Introduction  
A metasurface (MS) is a 2D metamaterial that has electromagnetic properties that do not exist in nature. In the last two decades, ag real deal of research has been conducted in the field of metamaterials and MSs, enabling fascinating electromagnetic properties that cannot be achieved with naturally occurring materials. In contrast to conventional materials, MSs provide a new way to manipulate microwave and MMW radiation based on reflection from sub-wavelength unit cell periodic arrays, which simultaneously have negative permeability and permittivity [1; 2; 3]. The unique interaction between the unit cells and the electromagnetic radiation aids in the design of innovative components. Applications such as metasurface perfect absorbers [4], cloaks [5], flat parabolic mirror surfaces (FLAPSs) [6], and polarization control [7; 8] have been demonstrated experimentally. In 1968, [PERSON] [9] theoretically investigated the electrodynamic consequences of a medium having negative values of both \(\varepsilon\) and \(\mu\), and concluded that such a medium would have dramatically different propagation characteristics stemming from the sign change of the group velocity. However, these effects could not be experimentally verified since substances with \(\mu<0\) were not available. The split ring resonator (SRR) medium proposed by [PERSON] et al. [10] provided the opportunity to make a material with negative permeability, from which a \"left-handed\" medium could be constructed. By combining the SRR with cut wire in an array structure, a left-handed material [11] was created. Reconfigurable metasurfaces (MSs) have attracted a great deal of interest in the last two decades. There are many interdisciplinary applications that have been realized by MSs [12]. Applications such as a millimeter-wave sensitive sensor MS based on a perfect absorber for the detection and recognition of micro-poisons in drinking water [13] and a W-band flat parabolic mirror for imaging systems and beam propagation [6] are resonant, and thus they are limited to a narrow bandwidth around the resonant frequency. Adding tunability to each unit cell significantly expands the performance and versatility of the MS for innovative applications. Reconfigurability of the MS can be realized by PIN switches [14], MEMS switches [15], liquid crystal or piezoelectric materials [16; 17], and varactor diodes [8]. The PIN switch enables MSs with a fast switching time, high reliability, low cost, and low voltage control [15]. Tunable components such as MEMS switches have attracted attention due to their small size and linearity; on the other hand, they have a relatively slow switching time compared to PIN switch diodes [16]. The discrete nature of switches cannot be used in applications where a continuous phase change is required. Liquid crystal (LC) changes the dielectric coefficient of the unit cell substrate by tens of percentage points as a function of applied DC bias. LC can be used at K-band frequencies and above [15]. LC has a slow response time compared to switches and varactors [18] and a small dynamic range relative to the varactor. A piezoelectric crystal allows limited flexibility proportional to the change in its physical size and requires a relatively high DC bias [17]. The varactor diodes enable a continuous and high dynamic range of capacitance, constant gamma for linear tuning, a convenient PCB assembly, and very low power consumption [19]. However, the solutions offered in the literature suffer from a bandwidth problem. This makes the task of finding an efficient and practical solution more difficult. Previous works, extensively based on CST simulation code, were implemented and experimentally tested for reconfigurable MS reflectors at Ku-band [20] and K-band [7]. The experimental results of these MSs are in excellent agreement with the simulation results for the reflection property values and beam-steering abilities. Based on those experimental results, we propose a new configuration concept named the stripes method.
