SpletRF Shielding Effectiveness. Shielding effectiveness is expressed quantitively as dB –20log 10 (E1/E2), where E1 is the value of the incident wave entering the shielding material and E2 is the value of the transmitted wave, that emerges from the shield (Figure 1). The result provides a value representing the reduction in emitted EMI/RFI. SpletA microstrip line shielded by via fences on a printed circuit board.
