A new ultrawide-bandwidth dielectric-rod antenna is presented with its application in detecting shallow targets, such as antipersonnel (AP) mines. The lowest hybrid mode is launched and guided along a circular-dielectric waveguide. The end of the wav

In this paper, the authors investigate an edge-based finite difference method based on the reduced dispersion finite difference method. In this method, an arbitrary stencil can be used to obtain a finite difference equation where optimal coefficients

In this paper, we review many of the sources of discretization error when finite methods is applied to high frequency electromagnetic problems. A major source of error is the numerical dispersion error. This error is probably the most serious error f

The growing occurrences of WLAN, BT, and FM on the same mobile device have created a demand for putting all three on the same die to save on die size, I/O count, BOM, and ultimately cost. Common blocks such as crystal oscillator, bandgap, and power m
