“…Extensive studies have been carried out of monochromatic plane wave and beam propagation in hyperbolic media [4,5]; also, of the reflection and refraction of plane waves incident on the interface of an isotropic and a hyperbolic metamaterial [6]. It has been established that a uniaxial anisotropic material with ε xr (ω) < 0 and ε zr (ω) > 0 exhibits negative refraction behavior for TM polarization for all incident angles, but the TE polarization behaves altogether differently [7,8]. Conditions have been derived for a uniaxial anisotropic plasma metamaterial to support a Faraday effect [9].…”

“…A two-dimensional (2-D) plasma photonic crystal is a structure in which plasma rods are arranged in the dielectric material periodically, or is a structure composed of dielectric rods in a bulk plasma (Sakai, Sakaguchi & Tachibana 2005;Sakai & Tachibana 2007;Sakai, Sakaguchi & Tachibana 2007b,c;Qi & Yang 2009;Qi et al 2010b;Qi 2012). Recently, the concept of plasma metamaterials was proposed, where the dynamic permittivity or negative refractive index can be manipulated by the tunable parameters (Sakai et al 2007a(Sakai et al , 2010Kong et al 2011;Guo 2012;Zhang, Liu & Kong 2013).

Using the transfer matrix method, absorbing properties of electromagnetic waves in one-dimensional plasma photonic crystals are proposed. Compared with the absorption of bulk plasma, more absorbing bands have been found in one-dimensional plasma photonic crystals, and the first absorbing band appears below the plasma frequency. These absorbing bands can be controlled by varying structure parameters, plasma parameters and the incident angle. Results show that the periodic number and collision frequency only control the absorbing magnitude. Plasma frequency, plasma thickness and incident angle affect both the absorbing magnitude and locations. Increasing the dielectric constant of the dielectric makes more absorbing bands appear. These features of one-dimensional plasma photonic crystals would have potential applications in tunable millimetre absorbers.

“…Unlike ordinary metamaterials, the dynamic permittivity of these materials can be manipulated by the external power supply used for plasma generation and the adjustable gas pressure and temperature. Besides, a negative refractive index can be obtained in plasma metamaterials [20,21] , and electromagnetic waves propagating through these materials may suffer significant deformation.…”

Plasma photonic crystals composed of periodic plasma and dielectric materials have attracted considerable attention because of their tunable photonic band gaps, but only their band structures or negative refractive index properties have been addressed in previous works. In this paper, through studying the transmission and reflection characteristics of two types of twodimensional plasma photonic crystals, it is found that plasma photonic crystals play an important role in absorbing waves, and they show broader band and higher amplitude absorption characteristics than bulk plasmas. Also, the absorption of plasma photonic crystals can be tuned via plasma parameters; varying the collision frequency can make the bandwidth and amplitude tunable, but cannot change the central frequency, whereas varying the plasma frequency would control both the location and the amplitude of the absorbers. These features of plasma photonic crystals have potential for terahertz tunable absorber applications.
