Interaction between a carbon based low-conductivity graphite microstrip, which is an element of a metamaterial, and incident electromagnetic (EM) waves was investigated in the microwave range of frequency (8–12 GHz). The distribution of the magneti
A metamaterial composed of thin metallic strips as an efficient broadband absorber in the mid-infrared spectrum is investigated. Here the matching between dielectric and geometrical properties of the individual elements is critical to ensure high abs

The resonant response of a thin conducting rod with a finite length irradiated by microwaves polarized along its axis is observed. By using a thermoelastic optical indicator microscope it is shown that rod with a length of several half- wavelengths c

The absorption efficiency of a conductive wire can be essentially increased in the broad microwave spectrum from 4 to 12 GHz by the appropriate choice of the radius and height of a wire. Such functional dependence ensures matching between the configu
We have shown that a structure composed of a semiconductor hemicylinder and a dielectric waveguide separated by a thin metal layer permits efficient and easy light control. In such a system, it is possible to ensure matching between TE and TM modes o

The excitation of standing TM waves by a subwavelength slit in the single-mode waveguide resonator with the metallic borders is considered. In this structure, the input energy through the slit strongly depends on the incident wavelength. Consequently
