Collapse of an axion scalar field

Abstract The manuscript deals with an interacting scalar field that mimics the evolution of the so-called axion scalar dark matter or axion like particles with ultra-light masses.It is discussed that such a scalar along with an ordinary fluid description can collapse under strong gravity.The end state of the collapse depends on how the axion Crysta

Planar ESPAR Array Design with Nonsymmetrical Pattern by Means of Finite-Element Method, Domain Decomposition, and Spherical Wave Expansion

The application of a 3D domain decomposition finite-element and spherical mode expansion for the design of planar ESPAR (electronically steerable passive array radiator) made with probe-fed circular microstrip patches is presented in this work.A global generalized scattering matrix (GSM) in FAT DIGESTIVE ENZYMES terms of spherical modes is obtained
