  • Isotropic Single Negative Metamaterials 

    Machac, J.; Protiva, P.; Rytir, M.; Blaha, M.; Zehentner, J. (Společnost pro radioelektronické inženýrství, 2008-09)
    This paper presents the application of simple, and therefore cheap, planar resonators for building 3D isotropic metamaterials. These resonators are: a broadside-coupled split ring resonator with a magnetic response providing ...
  • Universal Generator of Ultra-Wideband Pulses 

    Protiva, P.; Mrkvica, J.; Machac, J. (Společnost pro radioelektronické inženýrství, 2008-12)
    An Ultra-Wideband (UWB) subnanosecond pulse generator is described in this paper. High amplitude Gaussian pulses are generated by a Step Recovery Diode (SRD) included in a novel pulse forming circuit. The pro-posed circuit ...
