I have seen research showing metamaterials working on very-low-frequency electromagnetic waves, such as 60 hertz, and was wondering if metamaterials or other methods could be used to greatly slow electricity, without causing excessive resistance losses.
Light can be slowed down to less than one...
There are various methods to slow and even stop visible light. Most of these methods appear to be slowing the group velocity of light, not the phase velocity.
Can you slow the velocity of propagation of electricity? I have seen estimates that electricity, in a wire, propagates at 2/3 the...
So, is it correct to say that there will be some places of destructive interference and some of constructive interference, and that if you measured the microwave energy with a bolometer you would get the same energy while both 90 degree and 45 degree beams are on, as you would get by turning...
Suppose you have two coherent microwave beams, one beam at 45 degrees to a reflecting wall and the other one at 90 degrees, with the two beams pointing to the same point on the wall.
If the two beams are 180 degrees out of phase and destructively interfere at the point on the wall, will the...
Is there a way to use a Spatial Light Modulator or other device to remove high intensity light without removing low intensity (low amplitude) light from a physical object you are observing?
High intensity light would be completely filtered (removed) but low amplitude waves would not be...
How about attaching a device to the end of a narrow rocket and send the rocket down the 20" pipe to the bottom end of the pipe and let the device attach itself to the deepest end of the pipe, e.g., by opening an upside down metal unbrella so that the pressure of the gas and oil forces the device...
