Active shield structure

Various implementations described herein relate to an apparatus having a first coil-shaped helical structure for an active shield and a second coil-shaped helical structure wound between windings of the first coil-shaped helical structure. The first coil-shaped helical structure may provide a coil-based electromagnetic (EM) shield as countermeasure circuitry for protecting underlying circuitry. 本文所述的各种具体实施涉及一种设备，该设备具有用于主动屏蔽件的第一线圈形状螺旋结构和缠绕在该第一线圈形状螺旋结构的绕组之间的第二线圈形状螺旋结构。该第一线圈形状螺旋结构可以提供基于线圈的电磁(EM)屏蔽件作为用于保护底层电路的对抗措施电路。
