ABSTRACT
We begin by examining the differential time domain Maxwell equations in a linear medium: () ∇ × E = − ∂ B / ∂ t https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203736708/62790821-eaaa-4e82-9adb-20e3d4b3d9fe/content/eq1.tif"/> () ∇ × H = − ∂ D / ∂ t+J https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203736708/62790821-eaaa-4e82-9adb-20e3d4b3d9fe/content/eq2.tif"/> () ∇ ⋅ D = ρ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203736708/62790821-eaaa-4e82-9adb-20e3d4b3d9fe/content/eq3.tif"/> () ∇ ⋅ B = 0 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203736708/62790821-eaaa-4e82-9adb-20e3d4b3d9fe/content/eq4.tif"/> where () D = εE https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203736708/62790821-eaaa-4e82-9adb-20e3d4b3d9fe/content/eq5.tif"/> () B = μH https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203736708/62790821-eaaa-4e82-9adb-20e3d4b3d9fe/content/eq6.tif"/>
