GATE EC 2013 Question 61: Plane Wave Angle of Incidence & Electric Field (Electromagnetics)

EC > GATE 2013 SET-3 > Wave Propagation

A monochromatic plane wave of wavelength λ = 600 μm is propagating in the direction as shown in the figure below.

The angle of incidence θ_i and the expression for E_i are

60° and E₀(â_x - â_z)/√2 e^{-jπ×10⁴(√3x + z)/2} V/m

45° and E₀(â_x + â_z)/√2 e^{-jπ×10⁴√3z/2} V/m

45° and E₀(â_x - â_z)/√2 e^{-jπ×10⁴(√3x + z)/2} V/m

60° and E₀(â_x - â_z)/√2 e^{-jπ×10⁴√3z/2} V/m

Correct : c
