English: There was a H tangential which is a vector and a E_(z), these are the two unknowns, remember if you if you recall the surface integral equations, my variables back then were ∇ϕ.nˆ and ϕ these were my two unknowns right ϕ was my E_(z) and the other one was proportional to H tangential we had worked it out these were my two equations.
Telugu: H ​​టాంజెన్షియల్ అనే వెక్టర్ ఉంది మరియు ఒక E_(z), ఇవి రెండు తెలియనివి, మీరు ఉపరితల సమగ్ర సమీకరణాలను గుర్తుకు తెచ్చుకోండి, అప్పటి నా వేరియబుల్స్ ∇ϕ.
