例句與造句

1. Eigenmode expansion is a rigorous technique to simulate electromagnetic propagation which relies on the decomposition of the electromagnetic fields into a basis set of local eigenmodes that exists in the cross section of the device.
2. Eigenmodes are useful in constructing a full solution to the wave equation, because each of them evolves in time trivially with the phase factor e ^ {-i \ omega t } . so that a full solution can be decomposed into an eigenmode expansion
3. Therefore, the eigenmode expansion of the electric field is done not in plane waves but in the eigenmodes of the resonator which may be calculated, e . g ., via the transfer-matrix method in planar geometries; more complicated geometries often require the use of full Maxwell-equations solvers ( finite-difference time-domain method ).
4. It's difficult to find eigenmode expansion in a sentence. 用eigenmode expansion造句挺難的
