"Empire™ is a powerful, versatile and efficient 3D EM modeler that I use on a daily basis to design a wide

variety of RF hardware. It saves me a lot of engineering time which I now can spend on the more important

problems and ideas. Additionally, the excellent and encouraging support of the Empire support-team, which

are application engineers as myself, helps a lot to improve the effectiveness of my daily work."

"I use Empire since 2002 for solving different electromagnetic problems, such as microstrip antennas,

waveguide components, lenses, dielectric resonator antennas and artificial dielectrics. In all cases, Empire

turns out to be remarquably efficient and powerful tool, providing an excellent agreement between

simulations and measurements. Since Empire has a time-domain engine, it solves broadband problems much

faster than the Frequency Domain simulation tools I have used. The interface gives lots of flexibility and

control to the user and complex objects geometries can be programmed in Python without difficulty. The

technical support at IMST is very good and I always receive clear answers to my questions in very

resonable time."

"I have successfully used Empire to simulate antenna structures such as Dielectric Resonator Antennas

(DRA), slot fed patches, horns and lenses. I found the software to be a very powerful, fast and accurate tool

in predicting the performance of these antenna structures. As an example, Empire was able to accuratly

simulate the radiation pattern of a slot fed DRA array (paper attached). The learning curve was relatively fast

and the support of the IMST staff during this period was very good. The support staff at IMST is very

knowledgeable and was able to answer my inquiries within a short period of time."
