Computational electromagnetic is the well known field of research and generally used for solving EM problems numerically. CEM is very useful for designing the power systems. Antennas designed with CEM are specially used for biomedical applications. CEM is the field that uses computer simulation for solving EM numerical and it visualize the results with the help of graphs and tabular methods which were easy to analyze and the results will be compiled in an easy manner. CEM is generally applicable to all major categories such as antenna , microwave measurements.
Antenna Design gives the brief visualize of antenna elements. In this we can design antenna with predefined elements or arbitrary elements. It uses the method of moments to calculate port properties and surface properties like impedance and current distribution. We can design different types of dipole, monopole, spiral and patch antennas. We can easily refine and visualize the antenna’s performance in small steps and iterate until get the best result.
High Frequency materials are often used in the antenna design. There are many parameters of these materials that are beneficial for improved electrical performance. Understanding the parameters of high frequency materials allows designing the specific application with best results.
Microwave measurements techniques are required for microwave transmission. The quantities that are useful to measure change as the frequency is increased. For measurements frequency of oscillation are replaced by wavelength. Current, voltage and phase cease to be very significant in the microwave region.
Linear and nonlinear device are the main blocks for designing Radio frequency and microwave. S-parameters are mostly used to represent linear devices. Non Linear devices have been represented in simulation by SPICE models that operate in time domain. High frequency simulators analyze the linear and non linear networks.
