Consider a TE mode in a rectangular wave guide with a-2b (refer to figure in problem 1).Analyze the following statements
• The electric field of the TE10 mode has only component
• The H field of the TE10 mode is always perpendicular to the electric field E
• For any arbitrary cross section in the wave guide, the electric field of the TE20 mode is always orlented exclusively in the positive direction or in the negative direction
• The Index "m" in the TEmn modes indicates
In all TE modes the electric field is always parallel to one of the wavegulde walls in any arbitrary cross section Select]
In all TE modes the electric field is zero in the reglon very close to the waveguidewalls

Consider a air-filled rectangular waveguide with P.E.C. walls with cross sectional internal dimensions a=5cm and b-2.5cm. A TE wave of frequency f=25GHZ propagates along the wavegulde, with fields defined by
E_{y}=2 j E_{i 0} \sin \left(\theta_{x} x\right) e^{-j p}
H_{x}=-\frac{L / \mid-E_{0}}{\omega \mu} \sin \left(\phi_{x} x\right) e^{-j \mid t z}
H_{z}=-\frac{4 \sqrt{h} u}{\sigma \mu} \cos \left(\rho_{x} x\right) e^{-j p}
