"I'm pleased to the continuos development of the SEMCAD software. The usability has increased a lot from the first versions, in where many things were not possible or easy to do. Best thing is that the support is fast and when some new features are needed we have got a 'non-standard' version of the code and which has maybe later included in the software if widely usable feature."

"SEMCAD X is an excellent program to design hyperthermia applicators and to optimize the thermal dose that is delivered to the patient. Recently, we have introduced SEMCAD X as a standard fast, accurate and reliable planning tool for hyperthermia treatments. Tissue segmentations including radiotherapy tumour contours are semi-automatic generated and verified by a medical doctor. The interaction between electromagnetic fields and complex patient anatomies are simulated within a few hours by using the accellerated methods. The resulting SAR distributions are nicely visualized, such that they can be analyzed efficiently by both medical doctors and physicians. The technology of our treatments is rapidly improving and new features are fastly implemented by the great SEMCAD X support and development teams. The forum provides an excellent platform to share knowledge with other communities and to be up-to-date with the latest developments."

"We have been using SEMCAD to study microwave breast imaging. SEMCAD has a nice graphical user interface, intuitive to use, particularly for first time users.
Computation EM for complex structures can generate large files, which are difficult to manipulate and maintain. SEMCAD provides comprehensive and well-documented Python interface to interact both with its modeler and the solver. This allows us to write small script files to create/run simulations and extract results without the need to manage additional files."

"With the aim at the most reliable, accurate and professional EM simulation host in the world, SEMCAD always performs very well all the time. Here are somethings we'd like to share with you. First, it's extraordinary 3D GUI indeed helps any user from a beginner to an expert to be proficient in this full-wave FDTD simulator in a very short time. Second, compared with other commercial EM tools, SEMCAD is capable of providing more perspective and precise information to help designers understand the behavior, mechanism and the interrelation of any radiators, which greatly shortens the design process in the early development stage. Third, it's unique accelerator can largely reduce the simulation time by two-third compared with other simulators. It gives engineers more flexibility to execute, practice and study the design concept. Regarding the advantages listed above, we choose SEMCAD as the mainframe in our antenna design center!"

"I have used SEMCAD 1.8, 1.9, and SEMCAD X for many years to analyze biomedical engineering problems involving EM fields. The following are two examples of uses of SEMCAD.
In a study of cardiac pacemaker interference from cellular phone boosters I performed modeling of a complex, large linear antenna near a simplified model of a pacemaker with SEMCAD. The adaptive meshing capabilities of SEMCAD were used effectively to model very small, critical parts of the antenna within the relatively large problem space. The results were in close agreement with measurements by my team on the same system. The study was summarized in a paper presented at the IEEE EMC symposium 2004, entitled “High Resolution Computations and Measurements of Potential EMI with Models of Medical Implants and Radiating Sources” by H. Bassen and J. Casamento.
In another study I evaluated the specific absorption rate (SAR) distributions in a temperature sensitive pharmaceutical – insulin that was exposed to emissions from a 915 MHz RFID system. We used SEMCAD to determine the induced E fields and SAR in models of a single cylindrical vial and a group of nine closely spaced vials. The RFID antenna had several very small, critical parts that were modeled and meshed within the relatively large problem space, using the adaptive meshing capabilities of SEMCAD. We compared the modeling results with experimentally-measured SAR and obtain good agreement between the results of these two methods. The study was summarized in a paper Liquid Pharmaceuticals and 915 MHz Radiofrequency Identification Systems, Worst-Case Heating and Induced Electric Fields.

"SEMCAD X enabled us to determine the limitations of implant operation in human body with its built-in Thermal Solver. We are able to simulate the thermal effects in the head from the operation of a cortical implant without the need for any complex measurements. Thanks to the high resolution head phantom supported by SPEAG, the simulation results became much more realistic and accurate. We can identify the limitations for each implant design in advance, hence, avoiding iterative design and measurement procedures to achieve the final design. SEMCAD X is now a crucial part of our design routine, saving us significant time."

"LG electronics in Korea is always looking for innovative ways to improve our design and development processes to build the most feature rich, attractive and highest performance electronic products in the world. Part of that innovation relies on using the best computing technology available to run our software simulation tools. LG electronics is very happy with the performance of SPEAG's simulation platform SEMCAD X and Acceleware's solution, which employ Nvidia's latest GPUs for computation in addition to visualization. Simulation times for, e.g., a mobile phone that used to take ten hours, now only take 15 minutes to compute. This acceleration has opened up a whole new opportunity to reduce time to market and introduce new optimization algorithms into our processes. We look forward to new innovations from these companies that continue to accelerate our development."

"SEMCAD software is very reliable and has a user-friendly interface which encourages the novice to use it confidently from the very beginning. Its capabilities are greatly improved with the option of importing .SAT and .3DS files (among others), which allows the user to embed any shape or figure that was built externally into a SEMCAD-created model. The user is able to obtain almost any electromagnetic parameter he wants, and with a broad spectrum of plots and figures to represent them. I have found interesting the option of exporting figures as .wmf files, which allows obtaining high resolution printings. I feel very comfortable when working with this software tool."
