ABSTRACT:
A microwave antenna structure couples electromagnetic microwave energy from a microwave transmission line into a sample contained in a sample container without invasion of the sample. The microwave antenna structure is formed by a bifilar helix of conducting first and second helical elements. The first and second helical elements are arranged in a parallel relationship defining a double helix with alternating spaced apart helical turns from the respective first and second helical elements. The double helix forms a holder for receiving and holding a sample container within the turns of the double helix. The first and second helical elements are formed with coupling extension for coupling to opposite polarity conductors of a microwave transmission line. Electromagnetic microwave energy propagating along the transmission line is coupled into sample material within the sample container. A multiple sample microwave irradiation system provides an oil bath in the form of a reservoir containing relatively low dielectric constant fluid oil. A temperature regulator and circulator is immersed in the oil bath for uniform temperature control throughout the reservoir. Multiple microwave antenna structures and sample containers are suspended and immersed in the oil bath. Multiple microwave branch transmission lines couple microwave energy into the respective antenna structures.
