Combined microstrip radiators as unit cell of flat reflectarray antenna are represent combination of microstrip radiators located in aperture plane of reflectarray (transversal radiate elements) and also radiators vertically-oriented to this plane (longitudinal radiate elements). Advantage of the combined radiators in front of usual microstrip antennas is considerably. Firstly, using in aggregate transversal and longitudinal microstrip elements of the various form enable to reduce the dimensions of reradiators, that in turn allows to reduce distance between microstrip elements. It leads to miniaturization and to reduction in cost of all antenna system integrally. Also it allows to carry out scanning by radiation pattern in the expanded angular domain. Besides combined microstrip radiators without substrates satisfy to broadband response criterion it distinguishes them from microstrip antennas. Combined microstrip reradiators represent the significant interest for research and their use as elements of flat reflectarray antenna with the improved characteristics.

Submillimeter technologies now received increasing interest for scientific and commercial applications (e.g., imaging, security, biological, drugs and explosion detection, gases fingerprints, etc.) (see, e.g., [1–3]) and these technologies frequently need relatively simple room temperature or not deeply cooled (T≥80 K) broadband direct detection detectors [4].

Ground-based remote sensing of the atmosphere at millimeter waves is widely used at present for investigation of stratospheric ozone and other trace gases [1, 2]. Millimeter wave techniques in this investigation have to provide for both receiver low noise in the broad band of frequencies and low systematic instrumental errors which finally determine sensitivity of the system. In this paper we present the 3mm-wave radiometer designed for spectroscopic observations of atmospheric ozone and carbon monoxide thermal emission lines at frequencies from 90 to 116 GHz. The construction, observing technique and calibration method used are described. Ozone and carbon monoxide spectral lines were measured at frequencies 110.836 and 115.271 GHz, respectively. On basis of observed lines we have carried out the comparative analysis of the experimental and calculated sensitivity of the radiometer.

The localization length has been derived for one-dimensional bi-layered arrays with random perturbations in the widths or in the refractive indices for each type of layers. We explicitly take into account possible correlations in the disordered structures that can lead to anomalous frequency dependence of transport properties. Main attention is paid to the comparison between conventional materials and those consisting of mixed right-hand and left-hand materials. It is shown that the localization length is described by the universal expressions for both cases.

Layered Bragg structures are widely observed in nature and applied in engineering. Permittivity or/and permeability of layers are usually supposed to be periodical functions of space coordinate [1–3]. Distortions of periodicity supply additional possibilities for effects of wave scattering [4]. For obtaining desired complex amplitudes of scattered plane waves as function versus incident frequency or angle, spatial distribution of magnitude and phase of quasiperiodic perturbation can be used.

Quantum wells (QWs) CdTe/Hg1−xCdxTe/CdTe nowadays attract the considerable attention of scientists worldwide. These structures are considered to be very promising ones for creation of THz-detectors with improved performance which can operate without liquid helium temperatures cooling. In literature properties of such structures are investigated for the composition x=0 only.

A beam with launched field profile having Gaussian form is a good approximation for field distribution of HE11 mode which is the base oscillation type in quasi-optical hollow dielectric waveguides [1]. The beam scattering from layered structures can be studied by using the complex-source-point method [2]. Paraxial approximation is employed, when beam energy is assumed to be distributed in small angular domain [3]. In this paper we use the standard method of plane-wave Fourier spectrum representation [4] for simulation of propagation and interaction of 3-D beam with a scattering structure.

During the last time open dielectric resonators (DR) excited on whispering-gallery type waves due to their high Q-factor on the higher modes are used to investigate the dielectric properties of not only solid substances but also of liquids. For these purposes in the first experiments DR (which was used as measuring cell) being immersed directly in tested liquid. The investigated liquid influenced on external caustic of DR that led to frequency sift and changes of resonator Q factor. New achievement in creation of the dielectrometer measuring cells have appeared after the creation of the resonant structures in which certain geometrical parts of resonators are used. At first, such DR were created with metal mirrors. The subsequent researches [1] have shown that oscillations exist also without a mirror, which itself leads to condensate of a spectrum and reduction of the quality of resonator.

We describe the space-time distribution of the pulsed electric field in the middle atmosphere above a positive Γ-shaped lightning stroke. The current wave moves initially vertically and turns horizontally afterwards. Radiation arrives from the vertical electric dipole followed by that of the horizontal dipole. Combined with reflection from the perfectly conducting ground, the source generates three subsequent pulses in the atmosphere with the mutual lag depending on the velocity of the current wave. Pulses are multiply reproduced by reflections from the ionosphere and ground. The non-stationary fine structure appears in the spatial distribution of electric field, which persists for 2 ms and more. Estimates indicate on possible bunching of free electrons in the mesosphere. Focusing may occur at 10 km distance being delayed by a few ms from the moment of electron-field interaction.
