Outline of Final Research Achievements

A solid state oscillator with a capacitive mesh used as one of the reflectors in the resonator has been proposed as a new high sensitive tool which can distinguish small differences of dielectric constant in materials used in a terahertz frequency region. This measurement tool utilizes a surface plasmon resonance effect happened in the capacitive mesh. Theoretical and experimental analyses have been done at the frequencies between 75-110 GHz. The results have shown that the measurement tool can be used for materials containing water and can detect small differences less than 1E-5 in relative dielectric constants.
