Research and Development
EMC Consulting spends 50% of its efforts on R&D and many of the results are provided in reports available on this web site.
This R&D has covered:
 |
Shielding effectiveness of a suit made from conductive copper cloth. |
|
150Hz to 1MHz magnetic field coupling to a typical shielded cable above a ground plane configuration. |
|
Radiated emissions predicted and measured, from a voltage source in a 0.15m section of wire, (simulating a common mode voltage source in a PCB ground) and the effect of an attached wire. |
|
Transfer impedance of a shielded cable with the shield made from a Ni/Ag or Cu/Ni plated cloth tape. |
|
Conduit measured transfer impedance (20kHz - 1GHz) and shielding effectiveness (1MHz - 8GHz) (typically achieved in the RS103 and CS114 tests). |
|
Shielding a room using aluminum foil. |
|
The "magic" of magnetic field shielding of thin conductive sheet with a relative permeability of 1. |
|
Cable, connector and enclosure shielding effectiveness and transfer impedance. |
|
Coupling to cables. |
|
Radiation from cables. |
|
PCB radiation from different PCB layouts and with different IC drivers. |
|
Radiated coupling at microwave frequencies through a helicopter window. |
|
Radiated coupling between a transponder and a spectrometer on the SCISAT satellite. |
|
Crosstalk for TEMPEST and EMI considerations in connectors. |
|
Efficient EMI susceptibility/immunity test antennas. |
|
Small measurements probes. |
|
Power line Impedance Network with controlled impedance from 10Hz to 1GHz. |
|
CDNs and LISN for 3 phase 680V ac 200A power lines. |
R&D is charged at $135/hr.
