Testing Shielding Effectiveness

4 Tests for Measuring EMI Shielding Effectiveness

All electronic gadgets radiate energy in the form of electromagnetic and radio frequency waves. Sometimes, this emitted energy interacts with other devices in its vicinity causing the other devices to malfunction. With the dramatic proliferation of electronic devices worldwide, electromagnetic interference (EMI) and radio frequency interference (RFI) have become ...
