“…Since the concept of PPCs was proposed, its transmission characteristics have been the focus of research. Sakai et al first proposed the concept of PPCs, constructed a helium discharge plasma array at atmospheric pressure, and investigated the bandgap of PPCs by experimental tests and numerical calculations [1,2]; Fan [3] and Wang et al [4], used dielectric barrier discharge (DBD) with two water electrodes to obtain a two-dimensional PPC with tunable lattice arrangement and photonic bandgap; Wang et al [5] designed a threedimensional woodpile type PPC and calculated and tested its transmission characteristics; Zhang [6], Wen [7], and Wang [8] composed a PPC using plasma discharge tubes and tested and calculated its transmission and absorption characteristics; V. I. Arkhipenko et al [9] 2 of 13 obtained PPCs using neon glow discharge arrays, placed them in waveguides, and studied the transmission characteristics of PPCs at X-band; V. S. Babitski [10] obtained a PPC using argon pulse discharge at atmospheric pressure and also calculated and tested the transmission characteristics of PPCs. The results show that the properties of PPCs are similar to those of metallic photonic crystals at high electron density.…”

A plasma photonic crystal (PPC) was formed using an array of discharge plasma tubes. The transmission spectra and bandstructure of PPCs with different lattice types under different polarization modes were studied through simulation and measurement. To study the types of bandgap in PPCs, the bandstructure of the PPC is calculated using symplectic finite difference time domain (SFDTD), a modified plane wave expansion (PWE) method, and a finite element method (FEM) based on weak form equations. The bandstructure of the PPC is compared with the transmission curve results. The results show that the bandgap is stable in the PPC, and the experimental and numerical results of the transmission spectra agree well. There are different types of bandgap in the PPC; the bandgap under TE-like polarization is caused by localized surface plasmon (LSP) and Bragg scattering. The bandgap under TM-like polarization is caused by the cutoff effect of plasma on the electromagnetic wave and Bragg scattering. The lattice type also affects the position and number of the bandgap. The three methods have their advantages and disadvantages when calculating bandstructure. Therefore, it is necessary to combine the results of three methods and experimental results to accurately determine the bandgap type of the PPC.

“…It can be a significant time delay or an operation at low microwave power or an extra development cost. At the same time, the discharge plasma has a great potential for the application in microwave devices in the function of control elements due to its possibility for variations in size, geometry and density by changing the discharge current [1][2][3]. In this work, we demonstrate the ability to control the propagation of MW radiation at high (about 50 kW) power by one-and two-dimension (1D and 2D) EBG structures using the pulse discharges in argon or helium at atmospheric pressure.…”

Abstract.A plasma control of powerful microwave propagation through the 1D and 2D EBG structures is investigated. Pulsed discharges in argon (or helium) at atmospheric pressure are applied as the plasma inhomogeneities. Temporal behavior of electron concentration in discharge is determined. The timedependent transmission spectra of 1D EBG structure formed solely by plasma in the X-waveguide are measured. The amplitudes of short (~200 ns) powerful (50 kW) microwave pulses at frequency of 9.15 GHz are strongly suppressed (more than 40 dB) when they fall in the time interval of plasma structure existing. The propagation of these powerful microwave pulses through the triangle metallic 2D EBG structure with the plasma control elements is investigated too: when plasma acts as a compensator of defect in the front row of EBG structure the transmission in direction of 45 o quickly ceases (during a few tenth of nanoseconds), or one quickly arises, when plasma is as an additional defect.

“…Microwave pulse shortening was produced by a onedimensional electromagnetic band gap (EBG) plasma structure (in other words, electromagnetic crystal) formed in a WR90/R100 waveguide section by 3 discharges in the glass tubes filled by neon at pressure about 70 Torr [6]. These tubes were installed perpendicularly to the wide wall of the waveguide at 30 mm distance from each other (see Fig.…”

Interest to electromagnetic pulses propagation in matter with the group velocity much smaller than the speed of light in vacuum increases recent decades. Effect of group velocity reduction for a wave in a spatially periodic matter (natural crystal, photonic crystal, etc.) exists for different ranges and variety of waves (X-ray, optical, THz and microwave) due to generality of laws of wave diffraction. Multiple stu-dies report significant reduction of group velocity v gr of an X-ray pulse passing through a crystal, when Bragg diffraction occurs [1]. A neutron delay in crystal in conditions of diffraction was predicted and observed [2]. Slow light, which is a promising solution for time-domain processing of optical signals, is a subject for multiple studies [3]. Experimental observation of this effect for microwave radiation generated by an electron beam in the photonic crystal built of metal threads was reported in [4]. and its frequency response (b) In the present report the experiment to measure microwave pulse delay in a specially designed photonic crystal (spatially periodic structure built of metal rods inside a WR90/R100 waveguide of 1 m length) is presented. Each crystal plane comprises 3 copper rods of 1.25 mm diameter placed normally to the wider waveguide walls (Fig. 1, a). The crystal period d = 23.2 mm corresponds to the half-wavelength in the waveguide for 9.15 GHz frequency. The microwave field structure in the waveguide corresponds to TE 10 mode of a rectangular waveguide. Since the delay time is proportional to the length of photonic crystal, the number of periods N was chosen to be rather high (N = 33) to make the delay time convenient for measuring. The photonic crystal frequency response is presented at Fig. 1, b and shows some amplitude ripples, which number is determined by the number of crystal periods.Microwave pulse propagation in the photonic crystal was simulated by CST Microwave Studio [5] to define the incident pulse width making pulse delay effect evident. The simulation of transmitted and reflected pulses in time-domain was produced at the incident pulse duration from 4 to 30 ns. It was shown that delay effect is well resolved, when the width of the incident pulse is 10 ns and shorter. The time distance between maxima of transmitted and reflected pulses is about 23 ns (Fig. 2), that corresponds to pulse delay time W. Both the transmitted and reflected pulses have chain of equidistant peaks with time interval between adjacent those of about 2W.
