Aperture Field Bounds for an Azimuthally Symmetric Slotted Cylinder


  • Joseph T. Mayhan


The problem of specifying the minimum magnitude of the maximum electric field over an azimuthally symmetric slotted cylinder subject to the constraint of a specified radiated power into a given wedge angle is treated. Aperture bounds are presented for both the TE, TM and the general TE/TM excitation of the slot. The degree to which these bounds are attainable is discussed, and their relationship to uniform illumination of the aperture is examined. The problem of synthesizing a specified field pattern over the given angle is also treated.
