AToM (Antenna Toolbox for MATLAB) originated from project TA04010457 (2014-2017) of Technology Agency of the Czech Republic and is written in MATLAB as a semi-open code offering user-friendly operation through GUI or direct access to low level functions. The simulation core of AToM is based on Method of moments solution to field integral equations on wire, planar, and volumetric structures. Together with modal decomposition (characteristic modes), the source concept, feeding synthesis and powerful optimization package (FOPS optimizer), AToM presents unique tool for analysis and synthesis of antennas.
AToM also contains several add-ons, notable examples being the determination of fundamental bounds on antenna metrics, the design of optimal shapes via topology (shape) optimization and parametric strip generator. An extensive list of integrodifferential operators is available both in RWG MoM (2D surface code) and piecewise constant MoM (3D volumetric code).
