fdtd software

The principle of FDTD is to write the Maxwell two vector curl equation into a difference form, and use numerical method to find its solution. Assuming that the electromagnetic field is in the direction of x-axis, the electric field has only the z-axis method component and the magnetic field has only the y-axis direction. Two curl equations can be written in the following form The electric field and the magnetic field are written down in the form Co

background:1D FDTD implementation based on Formula 1.42 (EZ component), 1.43 (Hy component).calculates the electric field and the magnetic field component, which is produced by the Jz of the z-direction current slice, the Jz is located in the middle of two ideal conductor plates, the two plates are parallel and extend infinitely to the Y and Z directions. the parallel plate is 1m apart and the differential grid δx=1mm.The current surface density caus

the center difference quotient approximate error is least. In addition due to the forward difference quotient andThe backward Difference quotient approximation is 1 order accuracy, the center difference quotient approximate is 2 order precision, therefore the sampling interval changes from the Π/5 to the Π/10, the forward difference quotient and the backward difference quotient approximate error becomes the original One-second,and the center difference quotient approximate error becomes one-fou

Software can be roughly divided into: Free Software and non-free software Types of Free Software and non-free software.The following are some terms that are frequently mentioned when discussing free software. They explain which types overlap with others or are part of o

Software Engineering-software testing, Software Engineering Software Testing After the system is complete, it is time to test the system. This must have been the first system of acceptance. We are confident that the system will be accepted by the master. Once it comes to the master, nothing will happen, in addition, so

In the past, I have read many articles about the top ten essential tools for developing common professional software such as. NET and. Net programmers. Today, I don't want to introduce these professional software. I want to introduce some auxiliary software that is often used during development to help us complete better development. I recommend commonly used a

It takes more than two years to develop programs! Make a small summary! Status Quo, At present, many software companies in China are still working in small workshops! After receiving a project, let's discuss how to do it. After the boss decides to make a decision, let's split our heads! As a result, a project started, and everyone was busy in the early stage! Everyone has their own jobs (some companies are unevenly allocated. If there are idle people,

period, the CS is not, other industries worse. When the economy improves, CS lead. There's a representative billionaire who says, "Software will swallow the world." human beings just develop software, let the software command the machine, all other working bots will help you. You are the mouth cannon, these rich people use their own huge amount of money

The structure diagram proposed by Yourdon is another powerful tool for software structure design. A structure diagram is similar to a hierarchy diagram, and is also a graphical tool for describing software structures, in which a box represents a module with the name or main function of the module; the arrow (or line) between the boxes represents the calling relationship of the module. Because the formula is

During software development, I often encounter this problem: "When a software function is implemented, the business personnel say one set, and the software personnel say one set ". Here, we can find out a pair of friends who are both conflicting and dependent on business and software. What the business personnel and

It took me two nights to finish reading "software technology", which should be a non-technical computer book that I once again applauded after "programmer's Cultivation". Although it was just a waste of time, however, the problem solved my doubts. Software Engineering emphasizes the process of software development, while soft
