Coupling Power and Information to a Plasma Antenna

Investigation of Electromagnetic Propagation in Plasma Structures Through Eigenfunction Expansions and FDTD Techniques

“…where the second term vanishes because v × B is perpendicular to v, and therefore perpendicular to the operator ∂ ∂ p . For the first term, the divergence theorem can be applied as was done in equation (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). Now, however, because of the v factor in the vectorial product, the distribution function must fall off faster than 1 | v| 3 as | v| → ∞.…”

“…Using the continuity equation (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) for the divergence term,…”

“…The wave functions ψ 0 and ψ 1 can therefore be written as a linear combination of Bessel and exponential functions, viz. (2) n (k 0 ρ) e inφ , (3-4a)…”

“…where J n and H (2) n denote the derivatives of the Bessel and Hankel functions, respectively, and r is the relative permittivity of the dielectric cylinder. With the set of coefficients found, the electromagnetic fields at all points in space are fully characterized, viz.…”

“…A plasma dipole is an antenna with a radiating structure based on a plasma element instead of a metallic conductor [1][2][3][4]. The plasma, kept activated by an ionizing source, is the conducting material that acts as the source for electromagnetic fields, which can then be modulated and used to carry information in telecommunication links.…”
