Abstract :
The wavenumber of complex modes in lossless planar transmission lines inside a metallic box, with or without top cover, are computed using the transverse resonance method. Without the top cover, some leaky modes can be observed. When these open guiding structures are covered, it is shown that these previous modes generate either evanescent or complex modes, depending on the metallic enclosure position
