Extensive research has demonstrated that memristors or trigonometric functions can enhance the complexity of discrete chaotic maps. This article introduces a four-dimensional trigonometric-based memristor hyperchaotic map (4D-TBMHM). By combining memristors, sine, and cosine, 4D-TBMHM exhibits complex dynamical behaviors. Bifurcation multistability phenomena are using numerical methods. The demonstrates symmetric attractor self-growth based on iteration length for various system control...
Summary form only given, as follows. A bandpass filter with high selectivity and wide stopband is proposed using the dual-layer scheme. The hybrid microstrip/DGS cell introduced to obtain center resonance two close transmission zeros. Based on cells, an interdigital-coupled scheme employed achieve strong passband enhancement selectivity. To extend bandwidth, defected microstrip structure proposed. operated at f0 of 2.6 GHz exhibits excellent (i.e., attenuation slope 420.9 dB/GHz 484.9 in...
