摘要： The invention provides a transducer for use with a conical reflector in which the transducer comprises a frusto-conical radiating member that is coaxially positioned with respect to the reflector member. The half angles of the radiating member and reflectors are related such that every ray from a selected point of interest on the axis that is reflected from the reflector cone to the active surface of the radiating member intersects substantially normally to the active surface.Where the energy is directed to a point of interest distant from the reflector, the half angles are related in accordance with the formula ##EQU1## ; AND, WHERE THE POINT OF INTEREST IS ON THE AXIS, THE HALF ANGLES ARE RELATED IN ACCORDANCE WITH THE FORMULA ##EQU2## where .phi. = CONICAL REFLECTOR HALF ANGLE;.theta. = conical radiating member half angle;R = the radius of the reflector at a point where a ray from the point of interest is reflected normally to the surface of the radiating member; andS = the distance from the radius R intersection on the axis to the point of interest on the axis.
