چکیده
Abstract. A new class of fractional 2D Lyapunov systems described by the Roesser models is introduced. Necessary and sufficient conditions for the positivity and asymptotic stability of the new class of systems are established. It is shown that the checking of the asymptotic stability of positive 2D fractional Lyapunov systems can be reduced to testing the asymptotic stability of corresponding positive standard 1D discretetime systems. The considerations are illustrated by a numerical example.

In this paper a continuous wave (cw) spectrometer in the far infrared range covering frequencies between several tens Gigahertz and one Terahertz is presented. The spectrometer employed a coherent detection scheme and therefore measures both the amplitude and phase of THz radiation. First spectroscopic results of Si-wafer and a test Bragg structure are presented.
