    • An improved electromagnetic field shielding for electronic equipment is disclosed. The improved shielding is composed of meta-material, where the meta-material provides electromagnetic wave protection. The meta-material can be coupled to existing enclosures for electronic equipment. The meta-material provides a wideband negative permittivity or a wideband negative permeability, where a direction of propagation of incoming electromagnetic energy is reversed before the energy can induce currents on a surface of the enclosure. Enclosures with poor shielding protection can be used in conjunction with the improved shielding. The improved shielding thus provides protection against external electromagnetic fields without the need for apertures or tightly sealed seams.
    • 公开了电子设备改进的电磁场屏蔽。 改进的屏蔽由超常材料组成,其中超常材料提供电磁波保护。 超材料可以耦合到现有的用于电子设备的外壳。 超临界材料提供宽带负介电常数或宽带负磁导率,其中输入电磁能的传播方向在能量可以在壳体的表面上感应电流之前被反转。 屏蔽保护不良的外壳可以与改良的屏蔽结合使用。 因此,改进的屏蔽因此提供对外部电磁场的保护,而不需要孔或紧密密封的接缝。
