Abstract: Aiming at the grid mismatch problem in traditional sparse reconstruction algorithms for two-dimensional direction of arrival (DOA) estimation, this paper proposes a two-dimensional off-grid ...

Python library for working with 2D grids and numeric matrices. Provides easy-to-use classes for generic grids (Grid) and numeric grids (NumericGrid) with methods for reading, editing, iterating, and ...

SAXONBURG, Pa., Sept. 18, 2025 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), a global leader in photonics, today announced the development of a high-precision molded 2D lens array leveraging its ...

Two-dimensional (2D) semiconductors, materials that can conduct electricity and are only a few atoms thick, are promising alternatives to the conventional silicon-based semiconductors currently used ...

What is grid() in Tkinter? Okay, imagine your app is like a spreadsheet. You’ve got rows and columns. With grid(), you can tell Python: “Hey, I want this button in row 1, column 0.” And boom! It lands ...

Coherent Corp. has announced the launch of its 2D Collimator Array, an innovative optical assembly designed for use in optical circuit switches (OCS), which are increasingly vital for advanced data ...

Abstract: Grid-based methods are powerful in direction-of-arrival (DOA) estimation with irregular arrays, whereas the fast implementation in 2D case is an important but challenging work. In this paper ...

@doutriaux1 last issue before Labor Day! The grid stuff does not work as I expect it to work, so either I'm not expecting the right thing, or it's slightly buggy. I have failed to find some ...
