Yes, and anything above it too, due to leakage around the sides (satellites for example).
And if yes, wouldn't this make an excellent missile and air defense system?
I doubt it. The generators are likely to be huge, static things (think airport sized), the beams would be steerable through only a narrow angle, and you would probably situate them away from major population centres.
If I were America's enemies, I would counter our air dominance by developing new air defense systems -- energy beams of all types or rail guns or whatever. Instead of trying to put together a complex system that took us a half century to achieve in the air, try to leap ahead and make it so that anything that flies, dies. Thus negating our edge and returning it to a ground battle where our edge isn't as huge.
I am sure plenty of regimes would like to leap ahead of American military technology, especially air defense, but it's easier said than done :-)
Yes, high flux microwaves are hazardous to living things and electronics. However, missiles and military aircraft can be shielded against microwaves.
I've been doing some research into this field. I believe that microwave beamriders hold the key to low-cost SSTO. Here is a summary of my conclusions.
The transmitter antennas should not sit on the ground. They should be composed of several linked hexagonal airships, totalling about a kilometer in diameter, operating at about 10km of altitude, tethered by a long power line supported by intermediate balloons.
The effective range of the antenna would be less than 500km, therefore a full orbital launcher would probably have three transmitter antennas spaced about 600km apart. This would allow the spacecraft to accellerate to orbital speed over a 1800km trajectory
Although using liquid hydrogen as propellant would give the maximum ISP (about 1200), liquid ammonia is a much better choice, with its high density, low cost, and easier handling. Ammonia's ISP of about 800 would also be close to the ideal for minimum energy required for GTO.

Thanks! (Would that it were otherwise, or that I was mistaken...)
I agree that people always seem to be concentrating on the battles instead of the war. Why do you suppose that is? Heads in the sand, fear of sounding crazy? Having the same agenda, but not admitting it (acquisition of power)?
That is a good question. I think maybe there is a general perception that there is a general war, but that it gets forgotten for the local battles, or ignored for fear of fighting on too many fronts. And there is really no organization, no coordination, and worst of all, no support for each other.
All too often, for example, we adopt the, er, linguistic practices the Left forces on us. Why? Because to refuse gets one singled out for attack (even if only verbal) from the Left. And the rest of the Right doesn't often rally to the poor soul's defence.
And the attack may be worse than merely verbal. The Left has so greatly infiltrated the judiciary that all sorts of bizarre takes on laws (not to mention the laws themselves) abound these days -- singling out and punishing the poor soul who broke their code, or law. And remember, to the Left the law (a straight code) is not a necessary component of civil life, it's just another tool to be twisted into a weapon against those who stand in the way of their all-out war for power.
Before there were lasers (Light Amplification by Stimulated Emission of Radiation), there were masers (Microwave Amplification by Stimulated Emission of Radiation).
I don't know, but I suspect this is technically a maser beam, and is absent a light component.
Is there a known substance that can withstand the huge forces of concentrated microwaves on the reflector dish of a satellite launch?
