A magic tee (or magic T or hybrid tee) is a hybrid or 3 dB coupler used in microwave systems. It is an alternative to the rat-race coupler. In contrast to the rat-race, the three-dimensional structure of the magic tee makes it less readily constructed in planar technologies such as microstrip or stripline.
The magic tee was originally developed in World War II, and first published by W. A. Tyrell (of Bell Labs) in a 1947 IRE paper. Robert L. Kyhl and Bob Dicke independently created magic tees around the same time.

... The E-field of the dominant mode in each port is perpendicular to the broad wall of the waveguide ... The signals in the E-plane and H-plane ports therefore have orthogonal polarizations, and so (considering the symmetry of the structure) there can be no communication between these two ports ...

Famous quotes containing the word magic:
“Until it is kindled by a spirit as flamingly alive as the one which gave it birth a book is dead to us. Words divested of their magic are but dead hieroglyphs.”
—Henry Miller (1891–1980)
