## Abstract

An apparatus which includes a plurality of sub-atmospheric vehicular devices; a substantially high power microwave transmitter located on each of the vehicular devices; and a waveguide for directing microwave energy from the high power microwave transmitter to a point in free space. The microwave energy from the microwave transmitters is directed from each of the plurality of vehicular devices to the point in free space.

## Claims

### Claim 1

An apparatus comprising:
a plurality of sub-atmospheric vehicular devices;
a substantially high power microwave transmitter located on each of the vehicular devices, each of the high power microwave transmitters configured to operate in synchronized frequency, amplitude, and phase with each other;
a waveguide for directing microwave energy from the high power microwave transmitter to a point in free space; and
wherein microwave energy is directed from each of the plurality of vehicular devices to the point in free space.

### Claim 2 (depends on 1)

The apparatus of claim 1 wherein each microwave transmitter is synchronized by communicating with one another.

### Claim 3 (depends on 2)

The apparatus of claim 2 wherein each microwave transmitter is synchronized using an external synchronization station.

### Claim 4 (depends on 1)

The apparatus of claim 1 wherein the output is aimable and confined toward the point in free space where it will collide.

### Claim 5 (depends on 1)

The apparatus of claim 1 wherein the vehicular devices include at least one from the group of a tank, naval ship or aircraft, ground/planet based vehicle, or other platform or device attached to or set upon the ground to facilitate aiming and firing of the system.

### Claim 6 (depends on 1)

The apparatus of claim 1 wherein each of the high power microwave transmitters are operated in phase for creating standing wave resonance at the point in free space.

### Claim 7 (depends on 1)

The apparatus of claim 1 wherein the high power microwave transmitters are operated at the same frequency and amplitude for creating standing wave resonance at the point in free space.

### Claim 8

An apparatus comprising:
a sub-atmospheric vehicular device;
at least a pair of substantially high power microwave transmitters located on the vehicular device, each of the high power microwave transmitters configured to operate in synchronized frequency, amplitude, and phase with each other;
a waveguide being associated with each microwave transmitter for directing microwave energy from the high power microwave transmitter to a point in free space; and
wherein microwave energy is directed from the vehicular device to the point in free space.

### Claim 9 (depends on 8)

The apparatus of claim 8 wherein each microwave transmitter is synchronized by communicating with one another.

### Claim 10 (depends on 9)

The apparatus of claim 9 wherein each microwave transmitter is synchronized using an external synchronization station.

### Claim 11 (depends on 8)

The apparatus of claim 8 wherein the output is aimable and confined toward the point in free space where it will collide.

### Claim 12 (depends on 8)

The apparatus of claim 8 wherein the vehicular device is chosen from the group consisting of a tank, a naval ship, and an aircraft.

### Claim 13 (depends on 8)

The apparatus of claim 8 wherein each of the high power microwave transmitters are operated in phase for creating standing wave resonance at the point in free space.

### Claim 14 (depends on 8)

The apparatus of claim 8 wherein the high power microwave transmitters are operated at the same frequency and amplitude for creating standing wave resonance at the point in free space.
