Question 1

Current Integration

add detail / context

Answer 1

The current should be integrated only over the surface of the cube.

Question 2

Dispersion Anomalous Region

I dont really understand this card

Answer 2

• Group velocity maximum occurs where the denominator is minimal
• in the region where dispersion is anomalous
• around ω₀.

Question 3

Attosecond Pulses

Answer 3

Attosecond (as) = 10⁻¹⁸ seconds.

Question 4

Reflection and Transmission

add context or delete

Answer 4

Calculate reflection and transmission of EM waves across interfaces between isotropic, linear media.

Question 5

Brewster’s Angle

Description and formula

Answer 5

• The angle at which there is no reflected wave for p-polarized light.
• = tan ^-1 (n_2 / n_1)

Question 6

Total Internal Reflection

Answer 6

• Occurs when incident medium has higher refractive index and angle exceeds the critical angle.

> arccos (n_2 / n_1)

Question 7

Guiding Light

how is it done?

Answer 7

• Trapping light in a region of higher refractive index
• n₁ > n₂
