“…The dipole would be resonant at the lowest frequency of interest with trap pairs placed accordingly to achieve higher frequency resonances. Traps have also more recently been incorporated in frequency selective surfaces (FSS) [4][5][6] to provide dual-band, band-stop and band-pass operation. Although traps are effective they require physical breaks to be inserted in the conductor.…”

“…For secondary or higher ordered grating lobe suppression, according to the diffraction theory, the size and periodicity of the resonant elements should be smaller than the wavelength of the incident radiation, otherwise the resonant optical properties of the FSS structure may be related to the coupling between adjacent elements, thus depending on the angle-of-incidence (AOI) of the incoming waves. Several resonant classical shapes for FSS design, for example, a circular loop [3], square loop [4,5], hexagonal [6], and fractal geometries [7,8] have been discussed based on the applications.

“…To enhance the performance of FSS's to ensure the aforementioned issues, several researchers have investigated loaded FSSs [3,[13][14][15][16][17][18][19][20][21], which have been classified as active loaded and passive loaded FSSs. An active loaded FSS has been designed by implementing a tuning circuit as a part of the FSS pattern to switch the frequency response (reflections and transmission) from transmission to reflection and vice versa over the chosen frequency range [14].…”

“…However, for wireless security purposes, FSSs have been incorporated into the walls of buildings, which block the wireless local area network (WLAN) signals while passing the cellular phone signals [2]. Several resonant classical shapes for FSS design, for example, a circular loop [3], square loop [4, 5], hexagonal [6], and fractal geometries [7, 8] have been discussed based on the applications. Recently, the primary issue is to design a FSS, which is miniaturized and must be stable over the large AOI.…”

Azimuthally periodic wedge-shaped metal vane loaded circular ring frequency selective surface garima bharti 1 , kumud ranjan jha 2 , ghanshyam singh 1 and rajeev jyoti 3In this paper, the analysis and simulation of a novel geometrical structure of the frequency selective surface (FSS), which has been achieved through the conductive loading of the simple circular ring with wedge-shaped metal vanes has been discussed. The electrical performance and behavior of the proposed structure have been studied in Ku band (12-18 GHz) of the electromagnetic spectrum for satellite communication. We have radially optimized the proposed structure to enhance the performance, such as reflection and transmission bandwidth. We have also discussed the effect of incident electric field at 08, 108, 308, and 508 on the electrical performance of the proposed FSS. In addition to this, the effect of angular sensitivity on the proposed structure through increasing the number of conductive loaded wedge-shaped metal vanes is also explored. However, the structural parameters of the proposed FSS have been obtained through the synthesis technique. The analytical results obtained from the synthesis technique have been supported by the simulation results achieved through CST Microwave Studio as well as Ansoft high frequency structural simulator (HFSS), which are commercially available simulators based on the finite integral and finite-element technique, respectively. Furthermore, for validation of the numerical results, the Ansoft circuit simulator which is based on mixed potential integral equations (MPIE) and solved by the method-of-moment has also been used to obtain the reflection and transmission parameters through the values of inductance and capacitance, which have been achieved by the numerical analysis.

“…The FSS can either block or pass electromagnetic waves of a certain frequency depending on its specific shape or structure. Numerous different resonant shapes have been used for FSS design, for example a circle [1], square [2], hexagon [3] and fractal geometries [4,5]. An FSS can be designed to function with a high-pass, low-pass, band stop or band pass filter response.…”

Abstract-A novel 3D Frequency Selective Surface (FSS) architecture based on a circular ring unit element is presented. The circular ring was made 3D by creating a cylindrical element of a certain length, adding an extra degree of freedom into the structure. The length of the cylinder is shown through electromagnetic simulation to have a significant effect on the frequency characteristics of the FSS. Increasing the length of the cylinder can change the FSS from a band-stop to a band-pass filter response. The center frequency of both band pass and band stop responses can also be tuned with adjustment to the length. Dielectric materials are introduced in the center of the cylindrical unit cell elements to simultaneously obtain a stop and pass band with a sharp transition. For high dielectric filling materials, the 3D periodic structure exhibits negative refractive index metamaterial properties. A parametric analysis was conducted on these new cylindrical unit elements, and a prototype 3D FSS structure has been constructed and experimentally validated.
