Nonradiating surface sources.
The class of three-dimensional (3D) nonradiating sources to the inhomogeneous Helmholtz equation is generalized to include nonradiating surface sources that are localized on closed or infinite surfaces sigma and that generate no radiation throughout one of the two space regions whose common boundary is sigma. The class of non-radiating surface sources is shown to be identical to the class of so...
متن کاملTime Domain Analysis of Graphene Nanoribbon Interconnects Based on Transmission Line Model
Time domain analysis of multilayer graphene nanoribbon (MLGNR) interconnects, based on transmission line modeling (TLM) using a six-order linear parametric expression, has been presented for the first time. We have studied the effects of interconnect geometry along with its contact resistance on its step response and Nyquist stability. It is shown that by increasing interconnects dimensions...
متن کاملObservations on “Nonradiating Surface Sources”
The proof, established in a recent paper (A.J. Devaney, “Nonradiating surface sources”, J. Opt. Soc. Am. A, Vol. 21, 2216-2222, 2004), of existence of nonradiating surface sources formed by singlet plus doublet components whose generated fields vanish in either of the regions separated by a closed or infinite surface where the source resides is corroborated by means of an equivalent but slightl...
متن کاملDispersion properties of nonradiating configurations: finite-difference time-domain modeling.
A finite-difference time-domain (FDTD) numerical analysis is used to demonstrate that a toroidal solenoid, coaxial with an electric dipole, is a remarkable nonradiating configuration. It can be used to measure the dielectric permittivity of any ambient matter. It becomes a directional radiator at an interface between two dielectric media, depositing energy in the material with the highest polar...
متن کاملDescription of random radiating and nonradiating sources
An alternative description of spatially localized random nonradiating sources is derived, for any degree of spatial-temporal coherence. A description of a complementary class of random sources (purely radiating sources) that lacks a nonradiating part is also obtained.
