Developments in MetaMaterials

More Optical Metamaterials

Previous blogs have covered metamaterials for optics including an invisibility cloak.  Reference 1 moves into the shorter wavelengths of extreme ultraviolet (EUV) light.  It is interesting in that [..]

New transistors in the nano realm

The current structures for semiconductor central processing units (CPUs) are being designed and produced with some dimensions in the single digit nanometer realm.  Beside being hard to make, [..]

More nanomaterials, or is it metamaterials, or semiconductors?

Last month’s blog covered changes that are coming in the structure of semiconductor transistors.  With the announcement of 3nm devices [Ref. 1}, there is no uncertainty that the [..]

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 [..]

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 [..]

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 [..]

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 [..]

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 [..]
