41. Read't Hooft Polyakov monopole . 42. Several GUTs were proposed, most of which implied the presence of a real magnetic monopole particle. 43. There is no valid formulation for an equivalent concept for E0 ( electric monopole ) nuclear transitions. 44. :: That is a good point, so just ignore the monopole part with this question. 45. There are 4 monopole antennas on LS-1 : three UHF antennas and one VHF antenna. 46. It consists of a monopole antenna running parallel to a ground plane and grounded at one end. 47. So a monopole mounted over an ideal ground plane has a radiation pattern identical to a dipole antenna. 48. When the rear radiation is absorbed or trapped in a box, the diaphragm becomes a monopole radiator. 49. After all, another theory could come along that would explain charge quantization without need for the monopole . 50. Hence, the Dirac monopole is a topological defect in a compact U ( 1 ) gauge theory.
