a low impedance radiofrequency shielded window and radiofrequency shielded enclosure that includes the low impedance radiofrequency shielded window is disclosed . radiofrequency shielded window layers make up the overall window where the layers are configured in parallel such that each window layer has a direct path to ground . by configuring the ground path of the window layers in parallel , overall reactance and hence resistance is reduced , thus increasing shielding effectiveness of the window .
