Abstract: In this letter, a 180° rat-race coupler-based binary phase shifter is investigated for use in modern radar applications, such as phase-modulated continuous-wave (PMCW) and encoded radars.

X-ray diffraction measurements are consistent with this spectral change indicating a structural phase transition. For example, we find that the triplet ... We suggest a phase diagram for the PMN-xPT ...

The phase diagrams of Na2CO3 and K2CO3 have been determined with multianvil (MA) and diamond anvil cell (DAC) techniques. In MA experiments with heating, gamma-Na2CO3 is stable up to 12 GPa and above ...

The antihistamine desloratadine displays a two-step, reversible single-crystal to single-crystal phase transition during heating/cooling cycles between three conformational polymorphs: the low ...
