ANALYSIS OF N-SLOT STRUCTURE CORRUGATED HORN
N槽结构波纹喇叭的理论分析

The general formulas of characteristic equation and equivalent wall admittance of corrugated horn having N-slot structure are derived by using the space-harmonic analysis method. As a special example, the expression for equivalent wall admittance of corrugated horn having dual depth combination is presented. The equivalent wall admittance, eigenvalues, mode coefficients on horn aperture and radiation patterns have been computed fora corrugated horn having dual depth combination. The calculated radiation patterns are in good agreement with the measured values.
