Claims (1)

1. 44776/2 "WHAT IS CLAIMED IS: 1. A beam forming arrangement for forming a beam of wave propagated energy from the energy emitted by a source thereof , such arrangement comprising: a. at least a pair of mirrors having a common focal curve disposed around an axis of symmetry, one of such mirrors having a concave reflecting surface and. the other having, a convex reflecting surface to define a divergent channel for wave propagated energy, one of such mirrors being interposed between such channel and the common focal curve of such mirrors; and b. a source of wave propagated energy disposed between the confocal mirrors and within the divergent channel*adjacent to the narrowest part thereof.1 2. A beam forming arrangement as in Claim 1 wherein the cross-sectional shapes of the reflecting surfaces of each one of the pair of mirrors are segments of confocal parabolas having a common principal axis. 3.1 A beam forming arrangement as in Claim 2 wherein the principal axis of the confocal parabolas is parallel to the axis of symmetry.) 4. A beam forming apparatus as in Claim 3 wherein the principal axis of the confocal parabolas is inclined with respect to the axis of symmetry.' 5· A beam forming arrangement as in Claim 3 wherein the lengths of the mirrors vary.' 6. A beam forming arrangement as in Claim 1 wherein the reflecting surfaces of the mirrors are segments of confocal hyperbolas.' 7. A beam forming arrangement as in Claim 6 wherein the principal axis of the confocal hyperbolas is parallel to the axis of symmetry. 8. A beam forming apparatus as in Claim 6 wherein the principal axis of the confocal hyperbolas is inclined with respect to the axis of symmetry." 9. A beam forming arrangement as in Claim 6 wherein the lengths of the confocal mirrors vary.' &HEN ZEDEK & SiPISBA-C16
