TM0PECVertBC

A perfect electric conductor BC of the azimuthal component of the magnetizing field.

Overview

TM0PECVertBC is a perfect electric conductor boundary condition of the azimuthal component of the magnetizing field. TM0PECVertBC assumes an axisymmetric transverse magnetic (TM) wave.

The perfect electric conductor boundary condition of the azimuthal component of the magnetizing field normal to the antenna surface is

$var element = document.getElementById("moose-equation-642a6cdf-61d9-4f13-9e95-e44e02cffe13");katex.render(" \\textbf{n} \\times \\left( \\nabla \\times \\textbf{H} \\right) = 0", element, {displayMode:true,throwOnError:false});$

Where $var element = document.getElementById("moose-equation-1e6ef883-d8ac-40af-b091-8e0bfd73e85e");katex.render("\\textbf{H}", element, {displayMode:false,throwOnError:false});$ is the magnetizing field and $var element = document.getElementById("moose-equation-06e54501-0586-4e5d-8379-ff578c20c6a0");katex.render("\\textbf{n}", element, {displayMode:false,throwOnError:false});$ is the normal vector of the boundary. By assuming the normal of azimuthal component of the magnetizing field to the surface is purely in the axial direction, the integrated boundary condition simplifies to

$var element = document.getElementById("moose-equation-9848e95b-0ea6-43b5-83cf-ac785476d2ea");katex.render(" \\nabla \\text{H}_{\\theta} \\cdot \\textbf{n} = \\frac{\\text{-} \\text{H}_{\\theta}}{r}", element, {displayMode:true,throwOnError:false});$

Where $var element = document.getElementById("moose-equation-c51365a8-892a-44ae-90a1-47cc35c6aca1");katex.render("H_{\\phi}", element, {displayMode:false,throwOnError:false});$ is the azimuthal component of the magnetizing field and $var element = document.getElementById("moose-equation-19ec5e07-4168-4b78-b444-5b21513f36d2");katex.render("r", element, {displayMode:false,throwOnError:false});$ is the radial distance from the axial centerline.
