====Tutorial Lesson No. 1:========Analyzing A Center-Fed Resonant Dipole Antenna====[[FDTDLesson4]]
[[FDTDLesson4OLD]]
[[FDTDLesson5]]
===OBJECTIVE:===
To construct a center‐fed resonant dipole antenna in EM.Cube’s [[FDTD Module]], analyze it and visualize its near
and far field characteristics.
===YOU WILL LEARN:===
A simple half‐wave dipole antenna in free space will be analyzed in the first tutorial. This tutorial will guideyou through all necessary steps required to set up and perform a basic FDTD simulation and visualize andgraph the simulation results.[[PMOMLesson1]]
===We strongly recommend that you read through the first few tutorials and study them carefully before setting up your own projects.===[[PMOMLesson2]]
==1.1 Getting Started==[[PMOMLesson3]]
Open the EM.Cube application. Click Start, select All Programs, and then the EMAG program group. SelectEM.CUBE to start the program. By default, EM.Cube opens up a blank project with the name “UntitledProj1” inits [[CubeCADPMOMLesson4]] Module.

You can start drawing objects and build up your physical structure right away. Or you can initiate a new
project by selecting the New button of the System Toolbar (or using the keyboard shortcut Ctrl+N, or via
the menu File New Project…). This opens up the New Project Dialog, where you can enter a title for your
new project and set its path. You can use the Windows Explorer to go to the desired folder where you want to
place your new project folder. For this project, use the title “FDTDLesson1”. From the same dialog, you can
also set the project’s Length Units, Frequency Units, Center Frequency and Bandwidth. For this tutorial lesson,
set the length and frequency units of the project to Millimeters and Gigahertz, respectively, and set both the
center frequency and bandwidth to 1GHz. Then, click the Create button of the dialog to accept the settings. A
new project folder with your given name is immediately created at your specified path.
EM.Cube’s [[CubeCADPROPLesson1]] Module lets you construct 3D geometries, or import them via external model filessuch as *.stp, *igs, or *.stl. Once these geometries have been modified or completed, they can be moved toother modules within EM.Cube for further simulation. On the other hand, all modules of EM.Cube offer fullCAD operations by themselves. Therefore, you can build a new project from the ground up in any of EM.Cube’scomputational modules.
