Abstract

This paper reviews transmission anomalies of freestanding frequency surfaces (FSS), which are commonly used as filter and guiding structures in the far IR region. The effect is characterized by a sharp breakdown of the transmission factor in the passband and was first revealed by measurements. The paper demonstrates the numerical confirmation of these effects by computer aided calculations based on the method of moments combined with the Floquet theorem. The scattering characteristics are examined for different sets of parameters like the geometry of the structure, frequency, angle and polarization of the incident wave. The modeling with electric and magnetic currents allows the characterization of both patch and slot arrays.
