Testing CPT- and Lorentz-odd electrodynamics with waveguides
We study CPT- and Lorentz-odd electrodynamics described by the Standard Model
Extension. Its radiation is confined to the geometry of hollow conductor
waveguide, open along . In a special class of reference frames, with
vanishing both 0-th and components of the background field, , we realize a number of {\em huge and macroscopically detectable}
effects on the confined waves spectra, compared to standard results.
Particularly, if points along (or ) direction only
transverse electric modes, with , should be observed propagating
throughout the guide, while all the transverse magnetic, , are absent.
Such a strong mode suppression makes waveguides quite suitable to probe these
symmetry violations using a simple and easily reproducible apparatus.Comment: 11pages, double-spacing, tex forma
