The simplest forms of Lorentz transformation and Maxwell's equation

, 2002
用Clifford代数来描述 ,Lorentz变换和Maxwell方程组变得非常简单 .例如 ,Maxwell方程成为□F =4πj c,只一个方程就够了 .Formulating in terms of Clifford algebra,the expressions of Lorentz transformation and Maxwell's equations become very simple.For example,Maxwell's equation is □F=4πj/c,only ...

Strain‐Adaptive Dielectric Metamaterials via Bioinspired “Ligament‐Bone” Architecture for Ultrahigh‐Energy Capacitive Storage

Advanced Science, EarlyView.
A bioinspired strain‐adaptive ligament‐bone architecture achieves record‐high energy density of 26.1 J cm−3 and 90% efficiency at 600 MV m−1, coupled with a Young's modulus of 2.13 GPa. ABSTRACT Polymer dielectrics for capacitive energy storage face fundamental trade‐offs between breakdown strength, energy density, efficiency, and mechanical robustness.

Local Lorentz transformation and exact spherically symmetric vacuum solutions in

, 2013
In this paper a non-diagonal, spherically symmetric, tetrad field that contains an arbitrary function, S(r), which corresponds to a local Lorentz transformation, is applied to the field equations of f(T) gravity theories.
