Helix antennas for generators of short high-voltage pulses

2007 6th International Conference on Antenna Theory and Techniques, 2007
Distinctive features of high-voltage systems of generator and radiating antennas, that we developed, are: highest possible working voltage and electric field intensities in dielectric media of generator and antenna, limited from above by electric strength of dielectric media; possibility to connect small-size forming low-impedance output device of ...

Generalized spin helix states in quantum spin graphs

Physica Scripta
Abstract In general, the summation of a set of sub-Hamiltonians cannot share a common eigenstate of each one, only if it is an unentangled product state, such as a spin helix state in quantum spin system. Here we present a method, referred to as the building block method (BBM), for constructing possible spin-1/2 XXZ Heisenberg lattice ...

Helix Generation, Amplification, Switching, and Memory of Chromophoric Polymers

2007
The origin of biomolecular handedness known as homochirality in the animate world may be oneof the most puzzling issues among scientists. The cooperativity of amplification, switching, andmemory in biopolymers and synthetic helical polymers might be shared with ideas of a scenariofor the biomolecular homochirality, autocatalytic mechanism in chiral ...
