“…For the sake of brevity only the data associated to the cylindrical inclusions main axes (the z direction) are plotted and compared to the permittivity obtained using the derived equivalent Debye model, for each case. The agreement between the MGA and equivalent Debye is quantified by applying the Feature Selective Validation (FSV) technique [54][55][56][57], as required by the IEEE standard P1597. Furthermore, the difference between the effective MG permittivity and the derived equivalent Debye-like dependences are evaluated through the average error (AE )…”

Abstract-The paper gives an analytical transition from the Maxwell Garnett model of a biphasic mixture (dielectric host and dielectric or conducting inclusions) to the parameters of a singleor double-term Debye representation of the material frequency response. The paper is focused on modeling biphasic mixtures containing cylindrical inclusions. This is practically important for engineering electromagnetic absorbing composite materials, for example, containing carbon fibers. The causal Debye representation is important for incorporation of a composite material in numerical electromagnetic codes, especially time-domain techniques, such as the finite-difference time-domain (FDTD) technique. The equations derived in this paper are different for different types of host and inclusion materials. The corresponding cases for the typical combinations of host and inclusion materials are considered, and examples are provided. The difference between the original Maxwell Garnett model and the derived Debye model is quantified for validating the proposed analytical derivation. It is demonstrated that in some cases the derived equivalent Debye model well approximates the frequency characteristics of the homogeneous model based on the MGA, and in some cases there is an exact match between Debye and Maxwell Garnett models.

“…For this reason, only analytical results are presented for frequency approaching zero. In order to quantify the level of agreement between the comparisons, in accordance with IEEE Standard P1597 [36], the Feature Selective Validation Technique (FSV) [37], [38] Further analysis is presented in the frequency range up to 1250 MHz, although the investigations were performed also outside that band. It was observed that, at higher frequencies, the tested enclosure cannot be treated as an efficient shield.…”

Abstract:A new technique for approximate evaluation of a small slotted enclosure shielding effectiveness (SE) is proposed. The enclosure under test is equipped with a built-in, rotating, conductive stirrer, and the SE is determined for discrete angles of the stirrer position. The SE characteristics computed in the frequency domain for the enclosure with the stirrer are compared to those of the enclosure containing different arrangements of printed circuit boards. The paper concludes that the inclusion of an internal stirrer is a potentially beneficial approach to shielding effectiveness testing.

“…An EBG-patterned board with decoupling capacitors can be a means of both suppressing noise propagation from extremely low frequencies and minimizing the effects of the discontinuous plane [23]. Figure 12 reports the values of amplitude difference measure (ADM), feature difference measure (FDM) and global difference measure (GDM) evaluated by using the feature selective validation (FSV) technique [24][25][26] according to the recent IEEE Standard P1597.1 [24] for a significant quantification of the comparison between the measured and simulated values in Figure 11 …”

Abstract-In this paper, a tree-shaped power distribution network is designed based on constructal theory for planar EBG structure power plane on PCB, in order to optimize DC performance. Planar EBG structures suppress noise, and the network provides currents to them. This network is composed of hierarchical metal paths. The geometric parameters can be optimized based on the concept of constructal theory. The optimal performance consists of constructing the given area in a sequence of building blocks from the smallest size toward larger sizes hierarchically. In the meantime, a PCB power plane is developed with 2nd order tree-shaped constructal network. Analysis illustrates that EBG power plane with constructal tree shaped network has multifunctions of low voltage drop, current equidistribution and effective noise isolation.
