TheMinkowski sum of two setsA,B ∈ IR, denotedA⊕B, is defined as {a+ b | a ∈ A, b ∈ B}. We describe an efficient and robust implementation for the construction of Minkowski sums of polygons in IR using the convolution of the polygon boundaries. This method allows for faster computation of the sum of non-convex polygons in comparison to the widely-used methods for Minkowski-sum computation that d...

The electromagnetically induced transparency (EIT) effect is a quantum coherence between different atomic transition channels. absorption of the ensemble significantly reduced or even close to zero, and at same time, this accompanied by strong spectral dispersion near resonant frequency atoms, which widely used in group velocity control, light pulse storage, coherent manipulation on field. In s...
