Design of All Dielectric Frequency Selective Surfaces

Several all-dielectric surfaces are introduced in this paper aiming to obtain various stop bands between 6 and 12 GHz, and also demonstrating that filtering in the X band (8–12 GHz) can be achieved without the use of metallic structures. Properties of the structures have been assessed by full-wave simulation. The parametric analyses included in the research also showed that changing the geometrical parameters enabled the control of the working frequency. The performance of the proposed structures has been assessed through the reflection coefficient, whilst also dielectric resonator theory (interpretation of effective permittivity and permeability) has been approached to explain the operation of the proposed structures.
