“…In a conventional CPW, the metal traces are printed on a dielectric substrate surrounded by bottom and top free-space environments. However, in practical applications, ground plates are often added in order to increase the electromagnetic immunity of the device, to ensure the compatibility of CPW and microstrip technologies, to support thin and fragile substrate, and even to perform as a heat sink for active modules [15][16][17]. A CPW with a ground plate below the substrate is commonly called conductor-backed CPW (CBCPW) or grounded CPW.…”

In this article, the authors study the significant practical effects caused by the presence of a conductor plate beneath a coplanar waveguide (CPW) structure. Specifically the authors pay attention to the effects on the dispersion characteristics of the bound modes and on the signal integrity. This study allows one to discuss the reported proposal on the use of this additional conductor plate as an inexpensive alternative to air‐bridges in order to alleviate the possible spurious effects produced by the potential existence of asymmetries in CPW‐based circuits.

whereas the full FOV was recovered in the amplified image with the use of Fourier image amplification. Although the resolution at higher intensity levels was affected by the noise, the bar structure in the amplified image was detectable with the use of Fourier image amplification, but badly degraded with the use of direct image amplification. Figure 4 shows some results from data taken at 11.5 pW. The impact of beam fanning even at microwatt levels is clearly visible. Grating from scattering-induced coupling obscures the directly amplified images, but those amplified with the use of the Fourier method, although degraded, remain detectable.C. Experiment 2. It was of interest to determine a regime in which direct image amplification could yield a viable sustained amplified image and to study how those limits compared to similarly amplified Fourier distributions. In the second experiment, the pump beam power was fixed at 11.5 pW, and the beam ratio was varied over the range of 10"-104. Figures 4(a) and 4(b) show two of the directly amplified images after reaching steady state, where the total intensity Received 2-6-96 ABSTRACT This article describes a new type of externalplanar applicator with several patches. The new planar applicator has been developed for microwave hypertheimia controlled by microwave radiometp. The theoretical re-
