A mathematical model of a E-plane T-junction of rectangular waveguides with three-element monopole-slot coupling structure is developed based on an approximate analytical solution of an equation system for currents by a generalized method of induced electro-magneto-motive forces (EMMF). The characteristic feature of the T-junction model is that it simultaneously takes into account two factors: the...
Radiation fields of a radially oriented dipole located on a metal sphere coated with a thin layer of absorbing metamaterial are investigated. Numerical simulations were performed by using the electric Green's function for the space outside of an impedance sphere. An impedance of the metamaterial layer required to minimize the influence of the spherical scatterer with resonant dimensions upon the directivity...
