Retarded vector potential in antenna
Web23.1 Scalar and Vector Potentials for Time-Harmonic Fields 23.1.1 Introduction Previously, we have studied the use of scalar potential for electrostatic problems. Then we learnt the use of vector potential A for magnetostatic problems. Now, we will study the combined use of scalar and vector potential for solving time-harmonic (electrodynamic ... http://optics.hanyang.ac.kr/~shsong/Chapter%2011.%20Griffiths-Radiation-Dipole%20radiation.pdf
Retarded vector potential in antenna
Did you know?
WebThe loop is uncharged, so the scalar potential is zero. The retarded vector potential is For a point r directly above the x axis, A must aim in the y direction, since the x components from symmetrically pl aced points on either side of the x axis will cancel. (cos ' serves to pick out the y-component of dI'). Webantennas are directional antennas). Omnidirectional Pattern - a pattem which is unifonn m a given plane. Principal Plane Patterns - the E-plane and H-plane pattems of a linearly polarized antenna. E-plane - the plane containmg the electric field vector and the direction of maximum radiation. H-plane - the plane containing the magnetic field vector
