“…Unlike standard cubic splines, PCHIP splines exhibit discontinuous second derivatives at the knot locations. The PCHIP spline sacrifices this extra degree of 1 For close-packed, multibeam feed arrays, constraining the profile to be monotonic also ensures that adjacent horns can not interfere with each other. Both splines smoothly interpolate the monotonic knot data, but the standard cubic spline exhibits "undershoot" and "overshoot."…”

“…The number of frequency and model are m and n, respectively. Compared to the objective functions comprising the horn parameters [10,15], like sidelobe and symmetry, the approach of using multi-dimension distance can significantly reduce the time consumed in the process of repeatedly calculating the radiation patterns. Table 1 demonstrates the consumed time of every procedure in the MMT analysis.…”

Abstract-Design aspects of high efficiency profiled circular horn feeds with smooth wall for the high-power microwave (HPM) system are presented in this paper. The modal content at the circular aperture of horn necessary to closely approximate a linear polarized Gaussian distribution is established. Slope discontinuities along the axis of the horn are then used to generate the necessary waveguide modes with the appropriate amplitudes and phases at the aperture. The performance of the horn is calculated using the mode matching technique. Significant improvement in the performance of radiation over a straight conical horn can be achieved on the premise of high power capacity. The excellent correspondence between the simulations by MMT codes and CSTMWS (CST microwave studio) supports this conclusion.

336 Agastra et al.Abstract-By properly exciting higher order modes at an aperture it is possible to achieve higher aperture efficiencies. High efficiency antennas are mandatory in many applications, as discrete lenses, since the single element efficiency deeply affects the efficiency of the whole lens. In this contribution a genetic algorithm is applied to the mode matching analysis of square horns to achieve high radiation efficiency over a relatively wide band.
