hom kev tshaj tawm nrog qhov tsawg tshaj plaws txiav tawm yog hu ua hom tseem ceeb. TE10 yog hom tseem ceeb hauv lub voj voos xwm txheej.

Qhov twg ntawm hom twg yog qhov tseem ceeb hauv lub voj voos xwm txheej Mcq?

hom tseem ceeb nyob rau hauv daim duab plaub waveguide yog

'm' thiab 'n' sawv cev rau hom ua tau. Rau lub voj voos xwm txheej nrog b > a, TE_{01 yuav yog hom tseem ceeb nrog qhov tsawg tshaj plaws txiav tawm zaus.}

Yuav ua li cas yog hom dominant nyob rau hauv daim duab waveguide Vim li cas?

Plag: TE₁₀ yog hom tseem ceeb hauv daim duab plaub. Qhov no yog vim nws muab qhov tsawg kawg nkaus txiav tawm zaus uas yuav tsum tau muaj rau kev sib kis.

Yuav ua li cas hauv qab no yog hom tseem ceeb tshaj plaws rau lub voj voos xwm txheej?

hom tseem ceeb hauv lub voj voos xwm txheej yog

hom tseem ceeb hauv ib qho kev waveguide yog hom muaj qhov tsawg tshaj plaws txiav tawm zaus 'm' thiab 'n ' sawv cev rau cov qauv ua tau. Rau lub voj voos xwm txheej nrog b > a, TE_{01 yuav yog hom tseem ceeb nrog qhov tsawg tshaj plaws txiav tawm zaus.}

Puas te00 hom muaj nyob rau hauv daim duab plaub?

TE Modes in Rectangular Waveguide

TE₀₀ hom: m=0, n=1 Nws tsis tuaj yeem muaj , raws li tag nrho cov teb Cheebtsam vanishes. TE₀₁ hom: m=0, n=1 E_y=0, H_x=0 thiab E _xH_{y muaj.}
