A General Mode Matching Technique applied to Bandpass Radomes
(2001) In Technical Report LUTEDX/(TEAT-7098)/1-33/(2001)- Abstract
- A new method based on the mode matching technique and the finite element
method (FEM) is presented. The method can handle a general thick frequency
selective structure (FSS), that consists of an arbitraryn umber of aperture
layers and dielectric layers. An aperture layer consists of a conducting plate
with a periodic arrayof apertures. The order and the thickness of the layers
can be arbitrary. The aperture can have arbitrary cross-section, and these
cross-sections can be changed stepwise. The apertures can also be filled with
a dielectric material.

technique and cascade coupling. The fields... (More) - A new method based on the mode matching technique and the finite element

The method for the bandpass radomes is based on general mode matching
technique and cascade coupling. The fields outside the FSS and inside the
dielectric layers are expanded in Floquet modes. Inside the aperture layers
the fields are expanded in waveguide modes, which are calculated with FEM.
Bya mode matching technique, a scattering matrix is calculated for every
boundarysurface and a propagation matrix is calculated for everyla yer. These
matrices are cascade coupled to form a scattering matrix for the complete
FSS. The method has been verified bycomparison with other methods and
measurements. (Less)
