“…The manipulation of S-SRR dimensions leads to variations in its inductance and capacitance, consequently enabling the adjustment of resonance frequencies in accordance with Eq. (12). By positioning six S-SRRs with different geometrical parameters that correspond to different resonance frequencies on the back substrate of CPW, six peaks can be observed, as shown in Fig.…”

This paper presents an analysis of various split-ring resonator (SRR) configurations coupled with coplanar waveguides (CPW). Three distinct resonant structures are presented, namely, the S-shaped split-ring resonator (S-SRR), the conventional split-ring resonator (SRR), and a pair of SRR. Among the examined resonant structures, it is observed that the S-SRR exhibits the smallest electrical size with the corresponding resonant frequency of 1.37 GHz, while the conventional SRR has the largest electrical size with the corresponding resonant frequency of 3.34 GHz. On the other hand, the resonant frequency of a dual SRR is 2.37 GHz. However, the transmission coefficient of a dual SRR is -11.43 dB, which is higher than S-SRR (-10.02 dB) and SRR (-8.18 dB). Furthermore, this study extends the analysis between a square dual SRR and a circular dual SRR with retained area. The square SRR demonstrates a lower resonance frequency (2.23 GHz) relative to its circular counterpart (2.37 GHz). The comparison also shows that the transmission coefficient of the square configuration is -13.88 dB, which is higher than its circular counterpart (-11.43 dB). The realization of a barcode application is achieved by loading multiple S-shaped split ring resonators (S-SRRs) with varying geometric parameters adjacently onto the transmission line. By individually rotating each of these S-SRRs, it becomes possible to alter the notch magnitude, thereby positioning it within a specific designated range corresponding to a particular code. In the case of a configuration involving rotations of (0°, 45°, 90°, 0°, 45°, 90°), this approach results in the creation of a barcode denoted as "100 010 000 100 011 000". This methodology enables the encoding of information in the form of distinctive resonant responses, providing a versatile and compact means of realizing barcode applications.

“…It is named as such since the structure resembles the letter "S" The S-SRR does not exhibit a symmetry plane like the SRR. However, the S-SRR can be excited by contra-directional magnetic fields, and this phenomenon engenders the generation of current flowing in the same direction [12].…”

“…Also, the majority of multiband banstop lter design developed in the last decade were mostly concentrated on dual band and triband ltering responses [9][10][11]. In the literature, Split Ring Resonators (SRRs) are widely used in metamaterial cell con gurations where the concept of single-and doublenegative media can be exploited to recon gure bandstop lters to bandpass lters (and vice versa) in both technologies [12]. Moreover, metamaterials though SRRs help in achieving the miniaturization of a lter structure with low insertion loss, and high out o -band rejection [13].…”

Bandstop filters play an essential role in many radio frequency (RF) and microwave communication systems to block undesired signals or reject spurious harmonics. This paper presents the design and experiment of a compact quadband bandstop filter centered at 1.2/1.97/2.96/4.78 GHz with a passband insertion loss ranging from 1.07 to 2.9 dB. The overall volumetric size of the proposed filter is 0.197 λ g × 0.197 λ g × 0.01 λ g , where λ g is the guided wavelength at 1.2 GHz. The desired performance is achieved by introducing two diamond-shaped concentric split ring resonators (DSCSRRs) intercoupled and defected ground structure. The metamaterial properties of the DSCSRR have been verified by extracting and analyzing its effective permittivity and permeability. This research shows that DSCSRRs can generate multiband characteristics and yield high selectivity with good band-to-band isolation by generating transmission zeros between passbands. The filter is designed, optimized, and analyzed using High-Frequency Structural Simulator (HFSS). A good agreement is observed between simulated and experimental results. The measured results demonstrate that the proposed quadband banstop filter exhibits a minimum stopband rejection of 11.22 dB and fractional bandwidth greater than 4.51%, which makes it suitable for front-end transceiver components or multifunctional wireless systems to suppress unwanted signals at four separate frequency bands.

“…Metamaterials are artificial materials and in desired frequency, they may exhibit extraordinary electromagnetic properties (e.g., negative permeability, negative permittivity, reverse Doppler Effect and negative refractive) [1,2]. Due to these features, it takes place in many applications such as filters [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], antenna [23,24], absorbers [25,26] and sensors [4,5,13,14,16,18,21,22,27,28]. Split ring resonators (SRR) are one of the most preferred structures for electromagnetic metamaterials design [2-5, 8, 14, 18].…”

Split-ring resonator is a popular research topic in literature. As known, it may be used in the design of electromagnetic metamaterials. Additionally, these structures can be preferred in microwave filter devices. In this study, a band-stop filter was designed for GSM-900 and 2.4 GHz ISM band by using split-ring resonators. Two split-ring arrays (sizes of one of these arrays were larger than the other) were loaded on the transmission line and each array consisted of four identical rings. Thus, a dual-band pass filter was obtained and this filter covered the frequency of 0.91 (GSM) and 2.43 (ISM) GHz. Then, this proposed design was fabricated and measured. According to the measurement results, the fabricated structure operated at 0.93 GHz and 2.47. The experimental results were consistent with the simulation results. As a result, thanks to the proposed structure, two frequencies can be stopped at the same time. There is no need to design a different filter structure for each frequency.
