Forms of the equations of motion for the rectilinear, unsteady motion of a perfect gas, are systematically developed starting from the equations in the Lagrangian form, which are then transformed to relations between Jacobians. It is shown that a relation between the equation of mass conservation ...
The governing equations are given by Eq. (1.1). To keep our presentation clear, we minimize the number of the model parameters. To this end, we assume that all the inhomogeneities are of the same shape, size, properties, and orientation. All the matrix- and inhomogeneity-related quantities ...
From Equations (1) and (2), by comparing the measured absorptivities of the structures with and without graphene, decay rates can be obtained, and the absorption in the graphene layer and the remaining structure can be extracted. The absorption in graphene is: aG;Hybrid ¼ ðo À o0...
s equations but derived values. Thus, the minor modification we use here is to select the complex phase root corresponding to positivity in the imaginary part of effective refractive index, also fixing the dependent value of relative impedance. Two roots are then found for the fundamental quantitie...
In Equations (1)–(3), we know that when the surface impedance of the designed metamaterial structure matches the impedance of the air, the reflection of the metamaterial structure becomes 0. Therefore, when the impedance of the designed absorber structure meets Z = 1, we can obtain the refl...
It can be obtained from Equations (2) that when the resonance state (ω = ω0) occurs, the external leakage rate is equal to the internal loss rate of graphene (γe = δ). At this time, the critical coupling condition is completely satisfied, and the reflection coefficient is gone, ...
