A novel systematic synthesis method for negative group delay(NGD)filter is proposed in this paper. Transfer functions are obtain from synthesized characteristics polynomials. An optimum design condition is derived to reduce the number of resonators being equal to the highest degree of polynomial. Different synthesis examples are discussed with different orders and NGD responses. The exact agreement...
Cosmic rays are high energy particles travelling at near the speed of light. Unlike electromagnetic waves, they are subjected to the influence of magnetic field. Being small in size, some of these particles can penetrate through certain low-density metals with no ionization at all. Some of the cosmic particles will bombard with the atoms in the metal, forming positive ions. Aluminum and silver are...
