    Scattering properties of carbon nanotube antennas
    (Видавництво Національного університету "Львівська політехніка", 2009) Lerer, A. M.; Makhno, V. V.; Makhno, P. V.; Labunko, O. S.
    The boundary problem of diffraction and excitation of system of nanotubes-vibrators was reduced to solution of the integral equation (IE) with logarithmic kernel. After regularization the IEs were solved by means of collocation method considering th current’s behaviour at the vibrator's endings. The existence of resonances in the frequency range 0,1-1,0 THz was shown.

    The broadband multichannel UHF transmitting TV antenna
    (Видавництво Національного університету "Львівська політехніка", 2009) Kudzin, V. P.; Sannikov, N. J.
    The broadband multichannel UHF transmitting TV antenna consisting of shunt dipoles is offered. The antenna works on several frequency channels simultaneously. The detailed numerical and experimental research is carried out and the geometry of the antenna is optimized. The structure of the antenna includes two orthogonal planes of radiators, the power divider and matching device. The industrial sample of the aerial is created.

    The fast converging method of calculation of wire radiators in infinite planar phased antenna array
    (Видавництво Національного університету "Львівська політехніка", 2009) Kudzin, V. P.
    The effective fast converging method of calculation of wire radiators in infinite planar phased antenna array is developed. The method is based on use of Green’s function submitted as double series with accelerated convergence. The moment method is applied and piecewise sine basic and weight functions automatically satisfied to Kirchhoff’s current law are used. Expressions for impedance matrix elements consist of two series. Members of the series generated by spectral part of Green’s function are represented as the closed analytical expressions. Members of series generated by spatial part of Green’s function are calculated numerically by one-fold integration.
