Sentences with phrase «electromagnetic surface waves»

The underlying design approach has much wider applications, ranging from microwave to optics for the control of any kind of electromagnetic surface waves.

In the respective gap, the light beams of the waveguides initiate electromagnetic surface waves, the so - called surface plasmons.

Not exact matches

The high - performance photodetector uses so - called surface plasmon polaritons, highly concentrated electromagnetic waves at metallic - dielectric interfaces, to combine optics and electronics on smallest space.

Light from the stellar remnant, a neutron star located about 400 light - years away, is polarized, meaning that its electromagnetic waves are oriented preferentially in a particular direction like light that reflects off the surface of water (SN: 7/8/06, p. 24).

Imagine an electromagnetic wave moving through a flat surface made of thousands of tiny electrical cells.

In a new paper, electrical engineers at Duke University demonstrate the first completely dielectric (non-metal) electromagnetic metamaterial — a surface dimpled with cylinders like the face of a Lego brick that is designed to absorb terahertz waves.

The key to making light curve inwards is to make the shell's permittivity — which affects the electric component of an electromagnetic wave — increase smoothly from the outer to the inner surface.

Researchers from QMUL's School of Electronic Engineering and Computer Science, worked with UK industry to demonstrate for the first time a practical cloaking device that allows curved surfaces to appear flat to electromagnetic waves.

As soon as the electromagnetic waves of the light field hit the nanospheres, near - fields formed at the surface and began to pulsate.

(P6.2 lesson) 4.6.2.1 - Types of electromagnetic waves (P6.6 lesson) 4.6.2.2 - Properties of electromagnetic waves 1 (P6.7 a lesson) 4.6.2.3 - Properties of electromagnetic waves 2 (P6.7 a lesson) Required practical (P6.7 b lesson)- investigate how the amount of infrared radiation absorbed or radiated by a surface depends on the nature of that surface.

The propagating electromagnetic wave from the earths surface is now absorbed by the molecule which in turn adopts kinetic and thereby electromagnetic properties as the state of rest is now disrupted and its components vibrate, sending out electromagnetic waves as it struggles to balance its competing internal forces.

It cleverly heats up only the pan's surface using electromagnetic waves, which is why it's not only a super-speedy way to cook but also energy efficient.

Using electromagnetic waves to emit heat just to the pan surface, spillages won't stick to the hob surface and all you'll need is a damp cloth to wipe any stains away.
