ANTENNA DESIGN FOR ELECTROMAGNETIC WAVES PROPAGATION STUDIES THROUGH THE SALT ORE

Experimental analysis of dielectric properties of the salt and electromagnetic wave propagation trough salt ore can provide opportunities for a small astronomical observatory in a salt mine in Romania. Cherenkov radiation (generated by neutrinos) detection threshold is very low for the salt, and represents half of the ice one. Electromagnetic waves propagation is influenced by salt dielectric parameters (the relative permittivity and tangent loss angle). To select and measure the effects of neutrinos passing through the salt ore, electromagnetic measurements should be conducted under a very low level of radiations, like in the underground case.
