The experiment confirmed that the device was able to transform the light waves
in the range of frequencies that would have been absorbed by the optical filter, then completely reverse the process as the light wave
exited the filter, making it look as though the laser pulse had propagated through a non-absorbing medium.
Due to the nature of this interaction, engineers and scientists have long known that in order to reverse the process and make an object "invisible," the color of light waves
hitting the object has to be manipulated.
When viewing an object, what you are really seeing is the way in which it modifies the energy of the light waves
that interact with it.
After a brief calibration, the mirror sent light waves
that passed back through the chicken again and combined to re-create the "5."
MDF of a continuous plane light wave
propagating in vacuum at speed c is given by ([W.sub.0]c)/c = [W.sub.0][J/[m.sup.3]] where [W.sub.0] = [[epsilon].sub.0][E.sup.2.sub.0]/2 is the energy density of the light wave
and E is the amplitude of the strength of the alternate electrical field of the light wave
The researchers' goal was to design a structure that would predictably transform an incoming light wave
The light wave
can make many trips around the ring before it is absorbed, but only frequencies of light that fit perfectly into the circumference of the ring can do so.
As a light wave
travels from one medium, such as air, into another, such as water, it follows Snell's law: When light refracts, it does so on the other side of an imagined line perpendicular to the water's surface.
A light wave
with a--amplitude creates a--reflected color.
In it, the budding theorist imagines what it would be like to ride on a light wave
Just as motion changes the pitch of a sound wave, it can change the length of a light wave
. Light emitted by an object moving away from Earth appears to have its wavelengths stretched, or lengthened, as indicated by its spectrum.
That means that the electric and magnetic fields that make up a light wave
vibrate only in particular directions.
