“…Other skin effect models for lower frequencies are the cylindrical skin effect [27] and the f m -law with 0 < m < 1 as described in [26]. The general case including dielectric losses is discussed in [28] and [26], and a model considering a non-zero dc resistance of the inner conductor is presented in [29].…”

“…The approximative transformation (dashed curve), however, overestimates the CB current peak due to the frequency shift introduced in the Laplace domain (25). To improve the approximate solution, a simple scaling factor for the capacitor contribution (27), which is dominant in this case, is proposed and the result for a visually estimated scaling factor of 0.88 (dashed-dotted line) is illustrated in the same plot. The adjacent feeder contribution (31) remains unscaled.…”

“…The performance of the approximative solution, however, is improved by a larger capacitor, because its time constant τ C is higher and so 1 τ C smaller compared to the frequency s reducing the error introduced in (27) and (31) (c.f. Sections IV-C and IV-D).…”

“…The observed strobe was corrected, via deconvolution, to account for the measuring oscillocope transition duration (rise time), and the impedance mismatches at both ends of the wire line. The distortion of the strobe pulse by the miniature transmission line was determined to be negligible using response data in [13]. The corrected leading edge waveform for the strobe pulse at the input port of the shorted biconical line is given in Fig.…”

The theory and construction of the HP-1430A feedthrough sampling head are reviewed, and a model for the sampling head is developed from dimensional and electrical measurements in con junction with electromagnetic, electronic, and network theory. The model was used to predict the sampling-head step response needed for the deconvolution of true input waveforms. The dependence of the sampling-head step response on the sampling diode bias is investigated. Calculations based on the model predict step response transition du rations of 27.5 to 30.5 ps for diode reverse bias values of -1.76 to -1.63 V.

“…For example, it is well known that skin effect losses in shielded conductors and coaxial cables cause their step response to approach a final dc level asymptotically [2,3]. Since all physically realizable measuring devices require connectors, cables, wires, etc., transmission line effects on fast input signals are bound to occur.…”

The National Bureau of Standards' was established by an act of Congress on March 3, 1901. The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to promote public safety. The Bureau's technical work is performed by the National Measurement Laboratory, the National Engineering Laboratory, and the Institute for Computer Sciences and Technology.THE NATIONAL MEASUREMENT LABORATORY provides the national system of physical and chemical and materials measurement; coordinates the system with measurement systems of other nations and furnishes essential services leading to accurate and uniform physical and chemical measurement throughout the Nation's scientific community, industry, and commerce; conducts materials research leading to improved methods of measurement, standards, and data on the properties of materials needed by industry, commerce, educational institutions, and Government; provides advisory and research services to other Government agencies; develops, produces, and distributes Standard Reference Materials; and provides calibration services. The Laboratory consists of the following centers:
