By doping semiconductors, it is possible to create materials with specifically designed electromagnetic properties for waves propagating within them. The following 1-D plane wave at a frequency of 10THz propagates in a heavily n-doped silicon: Ē = Ẽ ejot = Ēejat e¯jyz At this frequency and the doping level, the conductivity of the medium is o=105 Sm'. The wave loses 3 dB of intensity (power) over a length of 184 nm. Assume the permittivity of the medium is purely real. Find a. the amplitude attenuation constant, a b. the relative permittivity of the medium, &, c. the wave velocity, v

Consider a GaAs LED with a refractive index of 3.66. The LED's surface is coated with a dielectric with a refractive index of 2.07. Some of the emitted photons are not transmitted due to internal reflection. What is the minimum angle of incidence for total internal reflection to occur? Express your answer in degree (º).

According to the book the answer is 29.8
