Metamaterials – Optics

In June’s blog, invisibility cloaking was covered.  While that is a type of optical metamaterial, the advantage of optical metamaterials is that they can provide the ability to extend the range of traditional optics.  (While the work has been ongoing … Continue reading

Metamaterials – Acoustic

Metamaterials are usually identified by indicating it is a constructed material that has characteristics not observed in nature.  As the last blog demonstrated, metamaterials at the nanoscale can be designed to work well in the optical and near-optical portion of … Continue reading

Metamaterials – Cloak of Invisibility details

Metamaterials are usually identified by indicating it is a constructed material that has characteristics not observed in nature.  While typically referring to nanoscale materials, there are metamaterials that are on the millimeter scale.  (That will be covered in a future … Continue reading

Metamaterials – Cloak of Invisibility

An excellent example of how metamaterials work comes from Stanford University [Ref. 1].  The concept can be described as creating nanoscale antenna to affect the performance of electromagnetic spectrum waves.  Over a half century ago, TVs had external metal antenna.  … Continue reading

What comes after nanotechnology?

In many cases semiconductor industry leads the application of technology shrinkage.  Each “generation” of new devices employs smaller and smaller dimensional structures in the circuitry.  There is work being done on qualifying the processes for the 3nm and 2nm generation.  … Continue reading

Metamaterials

What are metamaterials?  Why are they important to nanotechnology?  There was a recent article in the IEEE Spectrum Magazine that addressed the customization of material structures [1].  Meta is from the Greek and means beyond or after.  Metamaterials are materials … Continue reading
