WebbTimoshenko beam theory is applied to discribe the behaviour of short beams when the cross-sectional dimensions of the beam are not small compared to its length. Here in this project, we develop the theoretical formulation for three-dimentional Timoshenko beam element undergoing axial, torsional and bending deformations. Then we implement it WebbIn this letter, to verify that the shaped beam feed can enhance the aperture usage efficiency of a single‐offset parabolic reflector compact antenna test range (CATR), a shaped beam horn is proposed. First, we obtain the radiation intensity function of the feed. Then, a coaxial cavity horn feed with a half‐ring is designed to shape the illumination that …
