Abstract

Experimental measurements of the dispersion characteristics of a C-band helix structure were carried out and compared to the dispersion characteristics found from a helix model using the three-dimensional electromagnetic computer code MAFIA. A conceptually novel design comprising a helical thread of the same pitch and inner diameter in a cylindrical waveguide also were calculated with the MAFIA code. The helical-groove structure exhibits a smaller bandwidth but at a much higher frequency range than the traditional helical structure for similar physical dimensions. It is physically more robust in construction. The interaction impedance also compares favorably with those of the conventional structure. Index Terms - MAFIA, helix, interaction impedance, helical-groove.

Abstract

The European venture capital and buyout market has seen dramatic growth since the mid 1980s. UK funds raise ecu 4.9 billion between 1980 and 1992, according to the annual BVCA performance measurement study, mainly driven by medium-sized and large MBO funds. The UK private equity asset class has outperformed publicly quoted equities, and an important factor is its timely exit ability. The European M&A market continues to be active and IPO markets have become an increasingly attractive route.
