摘要:

AbstractUnder the assumptions of weak magnetic fields and temperatures well below the critical temperature of the superconductors, the propagation characteristics of a set of N coupled superconducting strips are calculated using an integral equation approach. The proposed theory provides accurate results for frequencies up to a few GHz. Magnetic field calculations allow us to predict acceptable values for the currents in the strips. Comparison with the propagation characteristics of aluminum strips demonstrates the major advantages of superconducting transmission lines, namely, negligible losses and dispersion, and higher phase velocities. Such properties are highly desirable in the engineering of fast interconnects for modern high‐speed integrated circuit

摘要:

AbstractIn the development of planar oscillator arrays for quasioptical power combining, it is desirable to know the relative phase of the individual oscillator currents or voltages. We present a simple quasioptical injection‐locking measurement which is used to determine the operating mode of a two‐device Ka‐band Gunn‐diode oscillator

摘要:

AbstractA new method capable of overcoming the limitations in coherent optical systems that occur when the optical source has a nonnegligible linewidth is proposed. The transmission of a reference signal derived from a common source allows the use of high‐power laser sources which are required in long‐haul optical syst

摘要:

AbstractSolutions of the unscreened slab line, the triangular slab line, the square slab line, and the hexagonal slab line are obtained by means of conformal mapping and the continuity of electric potential. Both the method and the results are new. All the solutions are believed to be virtually exact for all ranges of the ratio of the dimensions.

摘要:

AbstractA general, iterative method is described for obtaining voltage and current waveforms in a periodically driven nonlinear active circuit. This allows local oscillator modulation of the parameters of device models to be studied. The technique is applicable to both diode and FET circuit models, since it can accommodate multiple nonlinearities.

AbstractA finite‐element method for the analysis of 3D‐waveguide problems is formulated using a deterministic approach. The electric field is computed from the TE10excitation field by means of a variational formulation that satisfies divE= 0 even when field singularities ex

AbstractIn this article the method of lines is extended to solve the electromagnetic problems in cylindrical coordinates. It is shown that this method is both simple and effective in treating the calculation of cylindrical microstrips, striplines, and other related problems.

摘要:

AbstractA technique of fabrication and evaluation of microstrip lines onto undoped semi‐insulating (SI) GaAs substrates is described. The fabrication technique is based on the electroless plating of nickel flashed with gold. The evaluation includes the measurements of transmission and reflection properties of microstrip lines. The measured data for insertion and return loss are encouragin

摘要:

AbstractWhen an electromagnetic wave is incident on a dielectric body filled with active molecules, there also will be inelastically scattered waves in addition to elastically scattered waves. In this paper, making use of the expansion of vector spherical wave functions of Gaussian beams and the method of dyadic Green's functions, we analyze the problem of inelastic scattering of Gaussian laser beams by active molecules embedded in a two‐layer concentric sphere and we also give some numerical results for the first tim
