High degree of miniaturization with asymmetric rectangle resonators

In this conference paper, we discuss the spectral response of new rectangular asymmetric resonators and compare it to the characteristics of conventional circular structures. The rectangular design offers a miniaturization of more than 20% and features an improved transmission roll-off. Moreover, tips at the end of the resonator arms confine the electric field into a small area. Especially frequency selective surfaces or thin-film sensors, which rely on small outline resonators with sharp spectral responses, could benefit from these novel structures.
