Transcribed Image Text:**Problem 7:**
An infinite time-harmonic electric current sheet flows on the \(z = 0\) plane at the interface between two dissimilar materials, as shown in the figure. Find the resulting \(\vec{E}\) and \(\vec{H}\) fields in the two materials.
*Hint: Assume plane wave solutions propagating away from the current sheet and enforce the boundary conditions.*

**Diagram Explanation:**
The diagram illustrates the interface between two regions at the \(z = 0\) plane, where an infinite time-harmonic electric current sheet, denoted by \(\vec{J}_s = \hat{x}J_0\) A/m, is located.
- **Region 1** (left side):
- Material properties: \(\varepsilon_1, \mu_1\)
- **Region 2** (right side):
- Material properties: \(\varepsilon_2, \mu_2\)
The \(z\)-axis is horizontal, and the interface is represented as a vertical line at \(z = 0\), highlighting the transition between the two materials with different permittivities and permeabilities. The electric current sheet flows in the \(x\) direction.
