Abstract

Abstract A non-resonant microwave cavity shaped substantially in the form of a right elliptical cylinder, means for introducing microwave energy at one focus of the elliptical cavity and removing microwave energy at the other focus of the elliptical cavity; and means on the periphery of the elliptical cylindrical cavity for amplifying incident microwave energy and for retransmitting it; whereby microwave energy introduced into the cavity at one focus of the ellipse is amplified by a plurality of microwave amplifiers, and the amplified energy is delivered to the other focus in phase. Because the total distance from the input focus to the periphery of the cavity and back to the output focus is the same for all points on the periphery of the elliptical cavity. Alternatively microwave signals may be generated by a plurality of microwave generators at the periphery of the cavity, the generators being phased by microwave signals from the input focus of the cavity to cause high energy microwave signals from the generators to be in phase at the output focus of the cavity.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 61 words
In combination: a cavity shaped substantially in the form of a right elliptical cylinder; means for introducing energy into said cavity at one focus thereof; means on the periphery of said cavity for producing signals of greater amplitude than signals received at said periphery from said focus; and means, positioned at the second focus of said cavity for removing energy therefrom.
Claim 2
Dependent Claim 61 words
In combination: a cavity shaped substantially in the form of a right elliptical cylinder; means for introducing energy into said cavity at one focus thereof; means on the periphery of said cavity for producing signals of greater amplitude than signals received at said periphery from said focus; and means, positioned at the second focus of said cavity for removing energy therefrom.
Claim 3
Dependent Claim 13 words
Apparatus as recited in claim 1 in which said energy is microwave energy.
Claim 4
Dependent Claim 56 words
In combination: a conductive cavity, adapted to contain microwave signals, shaped substantially in the form of a right elliptical cylinder; a plurality of amplifying means, positioned on the periphery of said cavity; means for introducing microwave energy into said cavity at a first focus thereof; and means for extracting microwave energy at the other focus thereof.
Claim 5
Dependent Claim 56 words
In combination: a conductive cavity, adapted to contain microwave signals, shaped substantially in the form of a right elliptical cylinder; a plurality of amplifying means, positioned on the periphery of said cavity; means for introducing microwave energy into said cavity at a first focus thereof; and means for extracting microwave energy at the other focus thereof.
Claim 6
Dependent Claim 45 words
Apparatus as recited in claim 3 in which said amplifying means comprises a plurality of amplifiers, positioned on the periphery of said cavity to receive energy from said first focus of said cavity and to deliver amplified energy to said second focus of said cavity.
Claim 7
Dependent Claim 13 words
Apparatus as recited in claim 4 in which said amplifiers are diode amplifiers.
Claim 8
Dependent Claim 72 words
Apparatus as recited in claim 3 in which said amplifying means comprises a plurality of microwave oscillators positioned on the periphery of said cavity, phase locked with signals received from said first focus and adapted to deliver signals to said second focus, whereby signals from said plurality of oscillators arrive at said second focus in phase and large amounts of microwave power may be extracted from said cavity at said second focus.
Claim 9
Dependent Claim 13 words
Apparatus as recited in claim 6 in which said oscillators are diode oscillators.
Claim 10
Dependent Claim 35 words
Apparatus as recited in claim 3 in which said means for introducing microwave energy at said first fOcus and means for removing microwave energy at said second focus of said elliptical cavity are coaxial cables.
Claim 11
Dependent Claim 21 words
Apparatus as recited in claim 3 in which said elliptical cavity is non-resonant at the microwave frequencies introduced into said cavity.
