Riken group's EMI/ EMS Engineering Department is continuously conducting
research and development of advanced materials such as fine ceramics and amorphous
alloys. Combining our strength in materials technology with the high precision
simulation technology we have developed in-house, we are able to provide integrated
EMC technology solutions ranging from magnetic shields to radio frequency anechoic
chambers.
Riken group is recognized as one of the top suppliers of large-scale radio
frequency anechoic chambers in the world. To design and install these chambers,
Riken uses its extensive background in electromagnetic wave and high precision
performance simulation technologies. Combined with high performance radio frequency
absorbers, such as the hollow pyramidal absorbers and high frequency pyramidal
ferrite absorbers that have been designed by Riken engineers, we can optimize
each chamber's design to meet the varying performance needs of our customers.
To guarantee proper magnetic shielding, we use a variety of magnetic materials
including many developed in-house. With these materials and computer simulation
software based on actual environmental measurements, Riken group can offer its
customers optimum shielding solutions to magnetic noise disruption. One of the
materials developed and produced by Riken is 'Amorik,' a unique shielding sheet
that is highly permeable and provides excellent magnetic shielding at both low
and high frequencies. This material is sold as part of a kit (Amorkit) that consumers
can use to eliminate or reduce magnetic interference from computer monitors,
televisions and other devices that generate magnetic noise.
In addition to providing magnetic shielding solutions, Riken group uses
a broad range of conductive shielding materials to design and install optimum
e shield rooms for a variety of applications. In particular, Riken group has
abundant experience in designing electromagnetic free space for preventing radio
wave interference, malfunctions or Tempest (information leakage) events that
may occur in large open spaces such as broadcasting studios or computer rooms. |
