Light waves can be expressed as: y=acos[2π (vt-x/λ)]-----(1)
Can also be expressed as: Y=aexp[2πi (vt-x/λ)]-------(2)
In linear optics, the imaginary part has no meaning. In nonlinear optics, the sum of two conjugated e exponential complex numbers is to be written. ”
In fact, the imaginary part in linear optics is not meaningless, it mainly depends on the con

EMSs. FEKO. V7.0.1 x64+linux64 Three-dimensional full-wave electromagnetic simulation softwareFeko is the first commercial software in the world to bring this approach to market. This method makes it possible to analyze the problem of tvu accurately. The Feko supports the finite element method (FEM), and the MLFMM andFem mixed solution, MLFMM+FEM hybrid algorithm can solve the problem of the size of the large non-uniform media. Particularly suited to the problem of coupling between structures th
-Chip switching" application-specific ic asic. In addition to eight ports, MDS 9134 provides the flexibility to expand from 24 ports to 32 ports.
2 10-Gbps ports can be activated to meet the density requirements of the optical fiber switch above the rack and the edge access switch in the enterprise SAN. The product adopts a non-congested architecture and supports all 32 4-Gbps ports and two 10-Gbps ports running at the same time at the same speed.
The MDS 9134 provides 10-Gbps ports that suppor

1. LUN partitioning
LUN is just a logical thing. Within the storage device, the relationship between the LUN and the physical hard disk is like the relationship between the logical volume and the physical hard disk in the host, that is, the relationship between the LV and PV, in different categories. It can be understood that LUN is the logic driver on the Logical Disk after RAID.
But the difference is that LUN is a physical hard disk on the host.
The LUN is definitely not a hard disk. It is in

The next radial and linear gradients may not be the same as you might think, and in many applications there are two of similar tools that are used to create radial or linear Gaussian blur effects. The two tools for provocative images are more advanced, where you can build a filter using a radial and linear gradient, and the filter's effect can be adjusted by the options on the right. In short, it is not only to achieve the fuzzy effect, but also to adjust other parameters (satura
