Next Gen Nanomaterial-based Electromagnetic Interference (EMI) Shields
February 6 @ 11:30 am - 1:15 pm
Next Gen Nanomaterial-based Electromagnetic Interference (EMI) Shields
Abstract:
Electromagnetic interference is now a routine concern, as emitted radiation from a device can interfere with the function of nearby systems. The radiation can also be harmful to human health. Thus, shielding regulations exist in industrialized nations for all electronic products.
Most shields today are metal-based, and weight penalty of metals becomes an issue as devices and systems shrink in size. More importantly, metals do their shielding job primarily by reflection due to their excellent conductivity and the resulting large impedance mismatch between the shield and free space. This leads to undesirable secondary pollution.
This talk will focus on two ongoing aspects of EMI shield development.
First involves printing of shields which provides much thinner shields than what sheet metal fabrication can do. Shields based on alternatives to metals such as graphene and MXene are printed. Thinner shields translate to high absolute shielding effectiveness which is shielding effectiveness normalized to thickness and density. Printing also results in lower cost.
Second, the talk will focus on green shields that work by absorption rather than reflection, aiming at a green index much greater than one, where green index is the ratio of absorbance over reflectance.
