EMC
・Top-Class Delivery Achievements in Japan
・High-Performance Electromagnetic Wave Absorbers Developed by Our Own Company
・High-Accuracy Simulation Technologies
EMC (Electro-Magnetic Compatibility) refers to both EMI (Electro-Magnetic Interference), in which radio waves emitted by electronic devices do not interfere with other devices, and EMS (Electro-Magnetic Susceptibility), in which they are not affected by interference from other devices.
We develop and sell "anechoic chambers" and other products for measuring electromagnetic waves as part of our EMC-related business.
Topics
Highly Advanced Simulation Technology That Achieves Optimum Design
Utilizing equipment for evaluating absorbers and advanced computer simulation technology (Ray Trace Method/FDTD Method) developed by our own company, we design anechoic chambers of the highest technological level. Accordingly, it has become possible to build anechoic chambers featuring excellent site attenuation, radiation field uniformity and free space characteristics.
Ray Trace Mehod
This simulation method is based on radio wave propagation course calculations through the use of ray appropriation technology, inter-antenna connection calculation utilizing electromotive forces, and oblique-incidence characteristic calculations of electromagnetic wave absorbers using multi-stage composition models. Through appropriate utilization of expertise stemming from the accumulation of long-term measurement results, predictions of highly advanced anechoic chamber performance are possible.
FDTD Method
This method sets the differential Maxwell equation into Finite Difference, and solves the equation in the Time Domain. This software was developed by our company for designing anechoic chambers, and is applied in instances which predictions by means of the Ray Trace Method are difficult, such as in cases of compact anechoic chambers.
