Anteenooyinka waxay gudbiyaan ama helaan macluumaadka iyagoo ku faanaya tamarta elektromagnetic-ka. Sidaa darteed, tamarta iyo awooddu waa halbeegyo muhiim ah oo la xiriira hirarkan elektromagnetic-ka ah, waana lagama maarmaan in laga wada hadlo. Mowjadda elektromagnetic-ka waxay ka kooban tahay labadaba garoon koronto iyo garoon birlab ah.
Daqiiqad kasta, hirarka waxaa lagu sharxi karaa labadan vector. Jaantuska hoose wuxuu muujinayaa qaybaha korantada iyo magnetic-ga ee hirarka electromagnetic-ka.
Hirarka elektromagnetic-ga ah, garoon koronto ayaa ku toosan jihada faafinta, garoon birlabkuna sidoo kale waa mid ku toosan jihada faafinta, halka garoonada korontada iyo birlabku ay isku toosan yihiin.
Poynting Vector
Vektor-ka Poynting wuxuu qeexayaa tamarta hirarka elektromagnetic-ka ee waqti kasta oo cutub ah halkii goob ee cutub ah daqiiqad kasta. Waxaa markii ugu horreysay soo saaray John Henry Poynting sanadkii 1884 waxaana loogu magac daray isaga.
Qeexitaan: Vektor-ka Poynting wuxuu bixiyaa heerka wareejinta tamarta ee aagga cutub kasta.
Beddel ahaan: Tamarta ay qaado mowjad halkii cutub waqti halkii cutub waxaa bixiya Poynting vector.
Vektor-ka Poynting waxaa lagu tilmaamayS.
Cutubka
Cutubka SI ee Poynting vector waa watts halkii mitir labajibbaaran (W/m²).
Muujinta Xisaabta
Vektor-ka Poynting ee degdega ah, kaas oo qeexaya awoodda la xiriirta hirarka elektromagnetic-ka, waxaa lagu qeexaa sida:
halkaas ooEwaa vector-ka xoogga goobta korantada iyoHwaa vector-ka xoogga goobta birlabta.
Soo saarista Poynting Vector
Si aan si fiican u fahanno Poynting vector-ka, aan tallaabo tallaabo u soo qaadanno qaab-dhismeedkiisa.
Ka fiirso hirar elektromagnetic ah oo si toosan uga gudbaya aagga A oo u janjeera jihada faafinta (oo loo qaato dhidibka X). Inta lagu jiro muddada dt ee aan dhammaadka lahayn, hirarku wuxuu socdaa masaafo dx ah:
halkaas ooSwaa vektorka Poynting. Isla'egta kor ku xusan waxay bixisaa tamarta waqti kasta oo halbeeg ah halkii aag halbeeg ah daqiiqad kasta - kani waa macnaha jireed ee vektorka Poynting.
