“…[46] The lower phase angle of the AC EDLC reveals its increased ion diffusion lengths and electrical resistance in comparison with graphene/AC-based EDLCs. [47] In addition, the knee frequency ( f o ) at a phase angle of À45 , which distinguishes between the regions where the device's behavior shifts from purely resistive to capacitive, [48] is equal to 0.38 and 0.068 Hz for graphene/AC-based EDLCs and AC EDLC, respectively. The knee frequency of graphene/ AC-based EDLCs is %5.5 times larger than that of the AC EDLC.…”

Herein, activated carbon (AC) is composited with multiple weight ratios of graphene nanoplates through a facile and scalable technique, including sonicating and vacuum mixing in a slurry to fabricate pouch cell electric double-layer capacitors (EDLCs). Among the fabricated devices, the EDLC made of 2 wt% graphene/AC composite demonstrated the best electrochemical performance by enhancing the specific capacitance of AC EDLC from 27.3 to 39.3 F g À1 at 0.05 A g À1 current density. Moreover, the addition of graphene to AC leads to a more ideal capacitive behavior, reduction of charge transfer resistance (R ct ) of the AC EDLC from 2.04 Ω to below 0.05 Ω, and the decrease of the ohmic drop at a current density of 2 A g À1 from 18.7% to 5.7%. 2 wt% graphene was considered as the optimum amount to be added to AC to increase the specific capacitance on average by 40% and improve the capacitance retention to 97% after 1000 cycles at 1 A g À1 . Furthermore, the fabricated EDLC based on the optimum ratio of graphene to AC possessed satisfactory energy densities of 13.7 and 8.3 Wh kg À1 at 50 and 2000 W kg À1 power densities, respectively.

“…Pass-band (PB) of such systems begins in the low frequencies therefore these systems are widely applied as delay lines and deflection systems [1][2][3]. Since MSSs provide compact size and high efficiency in wide frequency range, these systems find applications in antennas [4,5], biomedicine [6], filters [7,8], phase shifters [9].…”

The algorithm of parametric synthesis of meander slow-wave system with additional shields is presented in this paper. The influence of main constructive parameters of meander slow-wave system with additional shields on its electrical characteristics was evaluated in order to achieve the optimal results of the synthesis. Verification of the algorithm of parametric synthesis of meander slow-wave system with additional shields was carried out using four different models of meander slow-wave system with additional shields grounded in different positions. Sonnet ® software package which is based on the method of moments has been used during the investigation.

-Constructions of meander slow-wave systems with additional shields grounded at different positions are presented. The construction of meander slow-wave systems with additional shields grounded at both edges is investigated in detail. The influence of the main constructive parameters on the electrical characteristics of meander slow-wave systems with additional shields grounded at both edges is evaluated. The main constructive parameters of the investigated system are: the length of the conductor, the width of meander conductor, the width of additional shield, and the width of the gap between adjacent meander conductors.Sonnet® software package, which is based on the method of moments, has been used during the investigation. The results of the influence of constructive parameters to the phase delay time, input impedance, and the width of pass-band of the system are discussed.
