Elma Offers AMC Injector/Ejector Handles

Elma Electronic is now offering advanced mezzanine card (AMC) injector/ejector handles. AMCs are the main boards for MicroTCA designs and are also implemented in some AdvancedTCA applications. The company's AMC handles feature precision milling, allowing tough tolerances to be achieved. Compliant with the latest AMC/MicroTCA specifications, the handles have a die-cast construction.

The ergonomic design features grooves to facilitate handling and positive detents at three positions. The Elma handles have an optional micro switch that fits all of the locations listed in the MicroTCA.0 specification. An optional light-emitting-diode indicator light guide is available with a die-cast zinc bright chromate faceplate.

The clear polycarbonate light guide snaps into the faceplate. Custom handle designs and colours are available and the customer's logo can be optionally integrated into the handle die-cast. Elma offers a range of other services, including silk screening, overlays and custom cut-outs.

Singula Now Handles Lossy Materials

Integrated Engineering Software has announced that the latest version of its Singula product for antenna analysis now handles highly lossy materials. Singula simulates the power loss that occurs as a result of the heat generation produced when lossy materials are exposed to electromagnetic waves The loss calculations can then be used by thermal analysis software to calculate the thermal distribution. Integrated's simulation software tools have been developed for engineers and scientists who design and model prototypes and need fast and reliable solutions.

Utilising computer simulation during the design process helps reduce the cost and risks associated with physical prototyping. Singula analyses all antennas including wire, surface and dielectric. RFID devices and bird cage coils for MRI applications are also modelled using this simulation tool. Other applications for Singula include scattering calculations, microwave circuits and shielding for Electromagnetic Compatibility and Interference (EMC-EMI).

Singula is a generalised hybrid method that combines the Method of Moments (MOM) with Physical Optics, and the Fast Fourier Transform (FFT) method to give engineers the option to choose the solver that best suits their needs. Engineers can select the MOM technique for midsize antennas, FFT for antennas requiring many wavelengths or, in special cases, such as reflector antennas, the combination of Physical Optics with MOM maybe preferable. Bruce Klimpke, technical director at Integrated, said: 'There are many applications that will benefit from the accurate handling of highly lossy materials, including stealth technology.

'In the military this technique is used with aircraft, ships and missiles to make them less visible to radar and other detection methods. 'In the biomedical field, an example would be an antenna radiating in the presence of highly lossy materials like biological matter, such as the antenna in a mobile phone.' Integrated's team of engineers and software professionals designed Singula to help solve a wide variety of high frequency electromagnetic field (EMF) problems.
