例句與造句

1. They can be modeled from the viewpoint of an effective dielectric constant, or an effective surface impedance.
2. When a texture is applied to the metal surface, the surface impedance is altered, and its surface wave properties are changed.
3. This structure can then serve as an artificial magnetic conductor ( AMC ), because of its high surface impedance within a certain frequency range.
4. Given the average surface current and the surface impedance, we could calculate the power dissipated as P _ D = 2 \ rho \ bar { J } ^ 2.
5. Second, AMC surfaces have very high surface impedance within a specific frequency range, where the tangential magnetic field is small, even with a large electric field along the surface.
6. It's difficult to find surface impedance in a sentence. 用surface impedance造句挺難的
7. The surface impedance is derived from the ratio of the electric field at the surface to the magnetic field at the surface, which extends far into the metal beyond the skin depth.
8. First one does high frequency calculations to optimize the shape and find the most important features, then small calculations to find the best surface impedances in the problem areas, then reflection calculations to design coatings.
9. To calculate the radar cross-section of such a stealth body, one would typically do one-dimensional reflection calculations to calculate the surface impedance, then two dimensional Fock calculations to calculate creeping waves circling around any smooth shadowed parts.
