Modification of the Schwarzschild optics for applications in hard X-ray imaging is discussed. The conditions necessary to achieve a high spatial resolution with two toroidally bent crystals in the Bragg geometry are formulated, and the focusing properties of the system are numerically simulated usin
## Abstract The use of an asymmetrical feed probe is shown to significantly increase the impedance bandwidth of a square planar monopole antenna. The feed probe is offset from the center of the planar element. The optimum location of the feed probe is shown to increase the impedance bandwidth by a
