Background. Many of the properties of metamaterials are similar to those found in the filter on mutually detuned frequency and unrelated resonators. The bridge filters are used as a low-frequency prototypes of such microwave filters. It is important to establish an analogy between metamaterials and filters on mutually detuned frequency and unrelated resonators for further development and design of new types of metamaterials. Objective. A central objective is a model development of metamaterials based on band-exclusive microwave filters on mutually detuned resonators, and the low-frequency-based prototypes. Methods. Characteristic equivalence test of metamaterials to microwave filters on mutually detuned resonators, their specific dependencies reveal (the modes in parallel channels, the locations of the attenuation poles above or below the bandwidth), manifested regardless of the types of resonators, the study of the possibility of the bridge filter prototypes using for metamaterials simulation. Results. The analogy between metamaterials and microwave filters on mutually detuned resonator is specified, the possibility of bridge bandpass filter use as low-frequency prototypes is shown. Conclusions. Microwave filters on mutually detuned resonators, and bridge band-pass filters as low-frequency prototypes, design techniques of which are well established, can be used for metamaterial modeling.

“…GA then assigns the boundary conditions and the floquet port excitation using the VB script and subsequently calls the HFSS to simulate the unit cell. After the simulation, the results are sent back to the MATLAB for calculation of the fitness value, which is given by Equation (2).…”

“…Metamaterials [1] are artificially engineered materials and have several unusual electromagnetic properties that are not found in ordinary materials such as negative refractive index, and artificial magnetism. They have myriad applications [2][3][4], and one of them is the design of Xband absorbers or radar absorbing material [5,6]. Several X-band absorbers have been proposed in the literature [7][8][9][10][11][12][13][14][15][16] that can be broadly classified into two categories: polarization dependent absorbers [7,8] and polarization independent absorbers [9][10][11][12][13][14][15][16].…”

Abstract-This paper presents a novel, Genetic Algorithm (GA) optimized X-band absorber using metamaterials. The unit cell of this structure consists of several square patches, each having a dimension of 2.5 mm × 2.5 mm. Their positions are optimized using the GA such that the X-band absorption is maximized. Simulation results and the subsequent experimental validation affirm that the structure offers absorption of 97% from 10.42 GHz to 11.98 GHz and absorption of 90% over the entire X-band from 8 GHz to 9 GHz and also from 9.35 GHz to 12 GHz, with peak absorption of 99.95% at 10.52 GHz. The results are compared with the existing ones, to demonstrate the superiority of the proposed design.

View full text Add to dashboard Cite

In this article an analytical solution of the problem of scattering of electromagnetic waves on bi-isotropic spherical shell has been presented. Secondary electromagnetic fields are introduced as a superposition of spherical vector wave functions. The solution of the boundary problem is reduced to solving a system of linear algebraic equations for the coefficients which are included in the presentation of the secondary fields. The formula to calculate the directional diagram of electric field in the far field and numerical results for different values of parameters have been obtained. The results may find practical application in the development and design of electromagnetic screens.
