Can a Metal Surface Repel Electric Charges?

We show that the interaction between a surface and a charge packet moving parallel to it can become repulsive above a critical relativistic energy. We find that this is true for a lossless dielectric surface and also for a Drude metallic surface-in apparen ...

Dielectric properties of K(Ta0.53Nb0.47)O-3 Single Crystal

Nava Setter, Petr Bednyakov, Daniel Rytz

Dielectric properties of K(Ta0,53Nb0,47)O-3 [KTN] single crystals with < 100 > and < 011 > crystallographic orientation were studied. Temperature dependencies of dielectric permittivity of monodomain and polydomain crystals of these orientations are compar ...

Tunneling and percolation transport regimes in segregated composites

Peter Ryser, Claudio Grimaldi, Biagio Nigro

We consider the problem of electron transport in segregated conductor-insulator composites in which the conducting particles are connected to all others via tunneling conductances, thus forming a global tunneling-connected resistor network. Segregation is ...

Soft and Flexible Antennas on Permittivity Adjustable PDMS Substrates

Anja Skrivervik, Jean-François Zürcher, Jovanche Trajkovikj

This work presents novel techniques for producing substrates for flexible antennas. The technique we propose is based on the use of an already existing and widely used substrate material Polydimethylsiloxane (PDMS), where the dielectric properties of the s ...

Slow magnetic dynamics and hysteresis loops of the bulk ferromagnet Co-7(TeO3)(4)Br-6

Ivica Zivkovic, Helmuth Berger

Magnetic dynamics of a bulk ferromagnet, a new single crystalline compound Co-7(TeO3)(4)Br-6, was studied by ac susceptibility and related techniques. Very large Arrhenius activation energy of 17.2 meV (201 K) and long attempt time (2 x 10(-4) s) span the ...
