Spatial Power Combining for

s the operating frequency of semiconductor solidstate devices increases into the millimeterwave region, the size of the devices and their power handling capability are reduced. In order to provide the advantages of a solid-state technology for moderate power levels at millimeter-wave frequencies, solid-state components must be combined. Spatial power combining provides enhanced RF efficiency by...

Scattering-free plasmonic optics with anisotropic metamaterials.

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...

Microwave Sensor Using Metamaterials

It is well known that electromagnetic wave can be applied to wireless communication, radar, heating and power transmission. It has brought human society into industrial and information age. The mechanism behind these applications is electromagnetic radiation, i.e. energy transportation and conversion. Recently, research shows that evanescent wave, which is non-radiation wave associated with gui...

Microwave and terahertz wave sensing with metamaterials.

We have designed, fabricated, and characterized metamaterial enhanced bimaterial cantilever pixels for far-infrared detection. Local heating due to absorption from split ring resonators (SRRs) incorporated directly onto the cantilever pixels leads to mechanical deflection which is readily detected with visible light. Highly responsive pixels have been fabricated for detection at 95 GHz and 693 ...

3d Printing of Anisotropic Metamaterials

Material properties in radio frequency and microwave regimes are limited due to the lack of molecular resonances at these frequencies. Metamaterials are an attractive means to realize a prescribed permittivity or permeability function, but these are often prohibitively lossy due to the use of inefficient metallic resonators. All-dielectric metamaterials offer excellent potential to overcome the...
