2D TLM Description
Free TLM simulation for your Mac 2D TLM is a free but complex simulation of a Transmission-Line-Matrix. Try to edit your own structure. It is not difficult to enter a new geometry into the mesh of the TLM applet. Click on the Edit button and open the edit window. Enter the width and height of the new mesh in the field nx= and ny=. Then press new/clear. The size of the mesh in the main windows changes to the new size. All structure elements entered previously disappear.Now, draw walls, fill in media, and set field excitations:Select the wall type. You can choose from an ideal electric wall, an ideal magnetic wall, and a simple absorbing wall. Use the mouse to draw the walls in the TLM mesh. The number of walls is not restricted. If you did a mistake and want to delete a wall, select the wall with a short mouse click. The selected structure element will become red. Then you can delete the wall with the delete item button in the edit window. If the first mouse click on the wall does not select the right element, you must repeat the the mouse click until the correct element is selected.If you want to use media in the structure, you have to activate medium in the edit windows and enter the desired media parameters. eps_r is the relative dielectricity, and g_loss is the loss factor of the medium. Use the mouse to fill the TLM mesh with medium. You can enter as many types and areas of media as you like. If you want to delete a area with medium, select the area (the selected area is marked with a red rectangle), and push the delete item button.The field excitation is very important. If you forget to set a field excitation in the TLM mesh, all field components in all TLM cells remain zero, and the simulation is rather boring. In this TLM simulator, the field can be excited with a time domain gaussian pulse. Select gaussian pulse in the edit window, then enter the parameters of the pulse. The field t_max contains the time step number of the maximum of the gaussian pulse. sigma corresponds to the pulse width, and ampl is its maximum value. As a rule of thumb, t_max should be at least three times sigma.It is possible to set more than one excitation in the mesh. Requirements: · Java
