If you want to do work against gravity, sure. But if you want to bend light with gravity you need a lot of mass! Translating the Earth's gravitational binding energy into measurable power is immense, and much more is needed to bend light, around say, a tin can large enough to hold you.
Your E field is your electric component of the electromagnetic wave, and your B field is the magnetic component. Gamma, or the photon, is the actual radiation. In a transverse wave they occupy the x, y, and z axis.
My question to you, since you have advertised yourself an expert and as such could help me with this problem, is what would be the orientation or rotation of the fields for a compression wave, often referred to as a longitudinal wave? If the axis is rotated, would the propagation then be directly effected by a magnetic or electric field?
Originally posted by yfxxx...if you want to say you need a lot of mass to gravitationally bend light, then you are obviously correct.
But then I never questioned that ! I only said that static electromagnetic fields can't bend light (quantum effects under really extreme conditions - so extreme that atoms can't exist - excluded).
First, there is no such thing as a longitudinal electromagentic wave in a vacuum (or any homogenous material). So any light travelling through space (or air) is always a transversal e-m wave. That's how Maxwell's equations work.
Second, I think a sort of longitudinal e-m waves can exist at material boundaries or in plasmas.
However, I don't recall the details at all, so I admit I must give this question a "pass". Sorry.
However, given what I said above (no "longitudinal light"), I don't see how it is relevant to the topic at hand ("cloaking" of secret spacecraft).

Finally! Now we are kind of on the same page!
Then how about this?
And don't criticize my link!
Well I can figger it out on my own, but I thought we could do some quasi-collaboration.

Boundary layers. I think that is where the answers are. Making the epsilon and mu values negative at the boundary layers.

I am willing to bet that it is in a polar orbit or something. It just doesn't seem feasible that they would want to allow it to orbit over western nations where people sit in their backyards with 16" scopes, looking for just such anomolies.

Sara, further to my email. Has the confirmation for the Melbourne HDD swap
with Aquila been signed yet. If it has we need to do the "back to back"
confirmation with EAF.
ENRON????
...
So is Enron mining Helium 3 on the Moon? No idea but if they are... we in big trouble...

Aquila, Enron and Koch are generally recognized as the first parties to
arrange and issue weather-related risk products into the U.S. starting in late 1996 and 1997. In 1999, the Chicago Mercantile Exchange (“CME”) launched the first public exchange-traded, temperature-related weather derivatives. Winter season heating degree-day (HDD) and summer season cooling degree-day (CDD) futures are traded on the CME for ten U.S. cities

Someone talking to the home office about heating degree day trading.
LAS VEGAS (AP) — British entrepreneur Sir Richard Branson said Monday he had all but given up hope that explorer Steve Fossett would be found alive.
Speaking on NBC's Today show, Branson described his friend Fossett as a remarkable individual who touched the lives of those he knew.
Fossett, 63, disappeared Sept. 3 after he took off from a western Nevada ranch in a single-engine plane on a search for suitable sites to attempt a new land-speed record.
"I think the chances are that he's no longer with us," Branson said. "I think everybody involved has pretty well given up hope, sadly."
n October 2003 the US Federal Energy Regulatory Commission placed 200,000 of Enron's internal emails from 1999-2002 into the public domain as part of its ongoing investigations. The archive offers an extraordinary window into the lives and preoccupations of Enron's top executives during a turbulent period
