circular waveguide

The smith plot (impedance circular diagram) is a tool for effectively selecting and calculating the matching impedance during design of the very high frequency and ultra high frequency circuits. The computation of complex numbers is simple, easy to learn, and is an effective tool for engineers in high-frequency fields. Smith diagram has been widely used in overseas radio design fields. This Smith Diagram CAD software is designed with most engineering

I wrote a two-way linked list in the previous article. Today I reviewed the circular linked list and wrote a circular linked list with a header node. The specific implementation is as follows: Node file (listnode. h ): template class circularlist; template class listnode { Public : friend class circularlist ; listnode (): m_pnext (null) {

IntroductionGraphic Display plays an important role in the development of industrial control systems. Compared with many dedicated configuration software, they have powerful graphics systems that can be configured with very beautiful systems. Today, many industrial graphics Development kits have to be paid, and many beautiful controls, such as instruments, can only look at the figure and sigh. A friend of mine made a monitoring system for a pumping station a few days ago. Due to the lack of rela

Android development: Uses Glide to dynamically load circular images and rounded images, According to the latest news, the famous Yelp application has also moved to the Glide camp. Besides, Glide works smoothly with Listview, Glide can cache images locally in addition to simple configuration, you can also pre-load the Listview image in advance to make the listview smoother. For details, see the blog post of Yelp. However, if you want to convert the lo

This is what my friends often ask me. Is a non-square button, that is, the circular, elliptical button control The first step is to create a Windows form control library and delete the usercontrol1.cs file. Add a new project, select the component library, and name it ellipsebutton. CS. Add two events in ellipsebutton. Designer. CS. The control length and text change events are displayed respectively. Add header files Using system. Windows. forms;Using

HDU 3264 open-air shopping Mols (Circular intersection area + two points) ACM Address: HDU 3264 open-air shopping Mols Question:Give some circles, select the center of one of the circles as the center of the circle, and draw a large circle, requiring the large circle to cover at least half of the area of each circle. Calculate the minimum area. Analysis:Enumerate each vertex, use two points to find the required circle, and update the minimum value.The

The first contact with Cashapelayer and Bezier curves, see the next Geek College video. It feels good for beginners.

Joseph Question:Number of 1~n n individuals in a clockwise direction around a circle, each holding a password (positive integer), the beginning of any choice of a positive integer as the top value m, from the 1th person in the clockwise direction from the beginning of 1 in order to count off, report m when the stop count. The man who reported M was out of the way, and his password was the new M-value, and the next person from his clockwise direction began to count from 1, and so on until everyon
