EMPIRE XCcel™ – developed by engineering excellence – is one of the leading 3D-electromagnetic field simulators. It is based on the powerful Finite Difference Time Domain method (FDTD), which has become an industrial standard for RF component and antenna design. Due to EMPIRE’s unique adaptive on-the-fly code generation it exhibits the fastest simulation engine known today. With this highly accelerated kernel full-wave EM simulations can now be performed in minutes which used to take days some years ago.
