Microwave oven is a closed cavity. so the waves present inside are not plane waves. However. in order to approximate the conditions of the oven wall. an equivalent metal sheet having the same thickness and area as the oven is exposed to the same power density applied in the oven. It is assumed that the entire area of the wall is 1 m2. operates at 2.45 GHz. and the wall is made of steel. A plane wave of 2.45 GHz is incident on a very large steel sheet. Steel has a thickness of 1 mm. a conductivity of 10 7 S/m. and a relative permeability of 200. The time averaged power density that collides with the sheet is 1000 W/m^2 and the wave collides perpendicular to the wall. Find the power consumed by steel per unit area.

A 2 V signal is incident to the interface from a 75 Ohm region propagating to a 50 Ohm impedance region. What is the reflection coefficient? What is value of the incident, reflected and transmitted wave? What voltage would you measure on either side of the interface right after the signal goes through the interface.
Imagine a two-dimensional system in which a sinusoidal waveform is excited at the exact center of a circular plate. The standing wave pattern is established when the excited wave two-dimensionalwaveforms for a stable equilibrium pattern of constructive and destructive interference with the reflected waves from the edge of the circular plate. Draw what you expect the standing wave patterns to look like in this two-dimensional system for increasing resonant harmonics, n. Explain what characteristics of the oscillating plate affect the value of those resonancefrequencies, and what geometric properties of the plate affect the patterns.
A 2 V signal is incident to the interface from a 75 Ohm region propagating to a 50 Ohm impedance region. What is the reflection coefficient? What is value of the incident, reflected and transmitted wave? What voltage would you measure on either side of the interface right after the signal goes through the interface. For the interface, I'm a little confused. I used a voltage divider and got V_transmitted = 0.8 and V_incident = 1.2. But shouldn't they be the same?

A flat luminaire with dimensions 1.2 x 0.2m is mounted in a ceiling. The fixture has an opal plastic plate at the bottom, and can be considered ideal diffused. On a wall in the room there is a picture with dimensions 0.4m x 0.4m, as shown in the figure. The measurements apply from the midpoint of fixture and picture. The luminous flux of the light source is 6200 lm. The luminous intensity normally from the bottom of the luminaire is 1400 cd. a) Determine the luminous flux going out of the luminaire. What is the luminaire's efficiency?
