Dual-band Sierpinski fractal monopole antenna [PDF]

, 2000
A new top-loaded reduced-sized dual-band (1.9 GHz and 3.5 GHz) monopole antenna for wireless communications is presented. The antenna provides better than -15 dB input return loss and keeps the same radiation pattern over both bands.

Design of millimeter-wave bandpass filters with broad bandwidth in Si-based technology [PDF]

, 2019
In this paper, a novel design approach is proposed for on-chip bandpass filter (BPF) design with improved passband flatness and stopband suppression. The proposed approach simply uses a combination of meander-line structures with metal-insulator-metal ...

Optimized absorbing boundary conditions for the analysis of planar circuits using the finite difference time domain method [PDF]

, 1993
It is shown that the description of absorbing boundary condition algorithms (ABCs) in terms of single incident plane waves does not provide sufficient information for choosing the best ABC for planar waveguide termination.

Inverse Statistics for Stocks and Markets

, 2005
In recent publications, the authors have considered inverse statistics of the Dow Jones Industrial Averaged (DJIA) [1-3]. Specifically, we argued that the natural candidate for such statistics is the investment horizons distribution.
