Smith (1905–1987) and is a graphical aid designed for use by radio frequency (RF) engineers to solve transmission line and matching circuit problems. Although computer-aided tools have grown steadily over the years, the Smith Chart is still widely used today, not only as a problem-solving aid, but as a graphical demonstrator of how RF parameters behave and an alternative to using tabular information. The Smith Chart can be utilized to represent many parameters including impedances, admittances, reflection coefficients, scattering parameters, noise figure circles, constant gain contours and regions for unconditional stability.
26) Again, in an isotropic material (properties independent of direction), B and H are in the same direction and μ is a scalar quantity. In an anisotropic material, B and E may be in different directions and μ is a tensor. 4. Permeability is not sensitive to frequency or temperature. Most materials, including conductors, have a relative permeability very close to one. 28) This is called the Lorentz force. The particle will experience a force due to the electric field QE, and the magnetic field Qv × B.
