Advanced Materials, EarlyView.Rozanov causality limit—a compulsive proportional thickness‐wavelength relationship (nd ∝ λ)—makes it challenging to develop perfect absorption with both thin thickness and low frequency. Herein, a cocktail effect in high‐entropy alloys (HEA) is crucially utilized for lowering plasma frequency to achieve epsilon‐near‐zero states, which finally enables ...

Advanced Materials, EarlyView.Coupling a dual‐gradient carbonized framework with Fe2O3/Fe‐N‐C catalytic sites enables spatially synchronized sulfur redox across the entire electrode thickness in high‐mass‐loading Li–S batteries. This synergistic structural–catalytic design effectively mitigates concentration, ohmic, and electrochemical polarization, thereby achieving high‐capacity ...

Advanced Materials, EarlyView.All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

Equivalent Circuits-2 Coupled Circuits
Transactions of the American Institute of Electrical Engineers, 1936An equivalent circuit to represent 2 coupled circuits having distributed self -and mutual impedance and admittance is developed in this paper for the general case, and modified for certain specific cases. The application of these equivalent circuits for representation of coupled power circuits or a coupled power circuit and ground wire or metallic ...

Equivalent circuits have been found valuable in the solution of certain problems in that they simplify the analysis. Furthermore, equivalent circuits provide a means of replacing magnetic coupling with simple impedance links thereby permitting the use of the calculating board for solution.

Transistor equivalent circuits
1996The first step in designing a transistor amplifier stage is to establish the D.C operating conditions by using a graphical method as shown in the last chapter. After this has been done, small signals which are applied to the input of a transistor circuit will be amplified with reasonable linearity.

Equivalent modulator circuits are developed in the form of linear resistance networks. They are equivalent in the sense that the current magnitude in any mesh of the network is equal to the current amplitude of a corresponding frequency component in the modulator.
