The status of the research on muon colliders is discussed and plans are outlined for future theoretical experimental studies. Besides continued work parameters a 3-4 0.5 TeV center-of-mass (CoM) energy collider, many studies now concentrating machine near 0.1 that could be factory s-channel production Higgs particles. We discuss various components in such colliders, starting from proton accelerator needed to generate pions heavy-Z target proceeding through phase rotation decay ($\pi \to \mu...
The article describes an innovative shaping procedure for the Gregorian ring-focus reflector antenna with two swappable feed units (horn and subreflector) a common flyaway terminal communication at C Ku bands. Over such multiband, main challenge is to achieve compact structure that meets stringent radio-frequency (RF) specifications. optimization carried out enhanced peak gain reduction of sidelobe level through rotationally symmetric subreflectors. Circular provides ease in manufacturing...
This article is concerned with analytical model for radiation pattern of a new double-flared diagonal horn antenna using “plane wave spectra technique 3D fields”. The accomplished by adding one more set flares in E- and H-planes equal flare angles into conventional horn. copolarized cross-polarized patterns E-, H-, D-planes have been computed utilizing the reported article. parametric studies on peak cross-polarization level carried out. performance horns same length aperture size are also...
An innovative multi-directional beam-steering shaping technique for offset Gregorian reflector antenna is described in this paper getting enhanced peak-gain. This applied at relatively shorter-focal length antenna, which could accommodate easily on shorter height spacecraft bus. Shaping reduces steering gain-loss over larger angle. In feed horn and sub-reflector are fixed only main moving. The results of obtained with physical optics method (PO) compared those using moments (MoM) good matching.
