Abstract: This paper investigates near-field extremely large-scale multiple-input multiple-output (XL-MIMO) systems with sparse uniform planar arrays (UPAs). Based on the Green’s function-based ...
Abstract: This paper presents a class of Ka-band rectangular waveguide (RWG) bandpass filter (BPF) employing periodic metallic post and mushroom-shaped arrays. The proposed RWG BPF configuration ...
// Useful for e.g. packing rectangular textures into an atlas. // Does not do rotation. // Not necessarily the awesomest packing method, but better than // the totally naive one in stb_truetype (which ...
