Abstract :
A novel microwave sensor based on rectangular waveguide filled with a double negative (DNG) material is modelled using a full wave electromagnetic commercial simulator CST. Simulating results show that evanescent mode are amplified and transmitted through the structured DNG materials within the frequency band that exhibits negative permittivity and permeability. Evanescent mode is sensitive to permittivity of dielectric material in the detecting zone. Comparing with the conventional microwave resonator, DNG materials-assisted microwave sensor allows for higher sensitivity.
