In this paper, we theoretically studied the tunable dynamic microwave properties of a magnetic skyrmion manipulated by strains through micromagnetic simulations.The strains are induced by voltage due to 4-Wheel Rollators the converse piezoelectric effect and then applied to modulate the dynamic characteristics through the magneto-elastic coupling e
The metal structures distributed in underground coal mine roadways can be equivalent to the receiving antenna to absorb electromagnetic wave energy and release the energy in the form of discharge sparks under specific conditions.The accumulated energy has the risk of igniting explosive gas.In order to solve ORG ALMOND OIL the problem, the condition
According to general relativity, astrophysical black holes are described by a small number of parameters.Apart from the mass of the black hole ( M ), among the most interesting characteristics is the spin ( a ), which determines the degree of rotation, i.e., the angular momentum of the black hole.The latter is observationally constrained by the spe
