this paper proposes a new smart antenna beamforming scheme based on electronically steerable parasitic array radiator (espar). the proposed method is capable of providing better capacity compared to the conventional espar. the termination of each antenna element in this structure comprises a pin diode in addition to a varactor. using pin diode besides the varactor provides more degrees of freed...
The Born-Oppenheimer Approximation (BOA) forms the basis for calculating electronically adiabatic potential energy surfaces, thus providing the framework for developing a molecular level understanding of a variety of important chemical problems. For surface chemistry at metal surfaces, it is now clear that for some processes electronically nonadiabatic effects can be important, even dominant; h...
A generalized structure that is capable of implementing power-law filters derived from 1st and 2nd-order mother filter functions presented in this work. This achieved thanks to the employment Operational Transconductance Amplifiers (OTAs) as active elements, because electronic tuning capability their transconductance parameter. Appropriate design examples are provided performance introduced eva...
