We use SPICE simulations to determine a response function of a two-diode 20-GHz sampling circuit. We explore the validity of the SPICE simulations in a variety
We use a general description of transmission lines to develop analytic descriptions for offset OSLT (Open-Short-Load-Thru) standards used to calibrate vector

In this paper, the current status of standards 1) for specifying cement-based materials to prevent deleterious reactions with external sulfates and 2) or
Time-and-polarization-resolved acoustic microscopy with an improved-spatial-resolution line-focus transducer of simply reduced active element width is applied
This work investigates the broadband propagation characteristics of transmission lines fabricated on silicon substrates of different conductivities. We compare

A versatile wear tester has been designed and built. The initial study showed that that with this tester, tes procedures can be developed to achieve clinically
This paper presents the current direction in the architecture of STEP (STandard for the Exchange of Product model data, ISO 10303). STEP is an international
