Abstract
Mode conversion from TE11 to TM11 modes in circular waveguides is investigated. It is found that an iris placed across the waveguide or an abrupt change in guide radius (step) will produce a wide range of mode conversion coefficients which can be used in most dual-mode feedhorn applications. The step discontinuity is found to produce relatively constant mode conversion over a wide band of frequencies.Keywords
