Figure 7(a) shows the directivity pattern of the sectorized array with the conical reflector in the 360[degrees] configuration obtained by operating each element of the array in pulseecho mode (using the 5077 PR) and measuring the peak to peak amplitude of the echo originated by a 20 mm cylindrical reflector located at 200 mm away from the transducer/conical reflector axis.
Directivity pattern of the 8 elements sectorized 400 kHz array measured with the conical reflector in the 360[degrees] configuration and in pulseecho mode using a cylindrical reflector (20 mm diameter) located at 200 mm distance and rotated 360[degrees] around the transducers in steps of 5[degrees] (a).
The CXR feed is designed to improve significantly the cross-polar accuracy of side/corner-fed single reflector systems, but is equally suitable for dual cylindrical reflector
Illahi and Naqvi studied the focusing from chiral nihility coated PEC and perfect electromagnetic conductor (PEMC) cylindrical reflector .

The electromagnetic wave radiated from the LFA is just reflected by the cylindrical reflector to a free space.
The cylindrical reflector means that the z coordinates on the XOZ plane are all equal as shown in Figure 4.

Now consider the relative RCS of a cylindrical reflector
and a comer reflector which would fit inside of it as shown in Figure 4.

Rather than using traditional dish-shaped telescopes, CHIME consists of four 100-metre-long cylindrical reflectors
which cover an area larger than five professional hockey rinks and gathers signals for the critical computational analyses supplied by the AMD FirePro S9300 x2 GPU cluster.
