dc.description.abstractA theoretical and experimental study is conducted to investigate the role of chirality in synthetic microwave absorbers. Three closely related anisotropic unit cells of thin wire objects, one chiral, one racemic and one non-chiral, are studied around resonance in rectangular waveguide. Conducting thin wire chiral and non-chiral objects, embedded in an absorbing dielectric host and positioned in rectangular waveguide, are numerically analyzed with the finite difference time domain method. Measured and predicted results for the scattering parameters are presented.
