Maxwell’s equations in time domain: differential and integral form. Maxwell’s equations in frequency domain: differential and integral form. Boundary conditions.

Constitutive parameters. Plane waves in time domain. Polarization of a plane wave: linear, circular and elliptical. Plane waves in frequency domain. Dispersive and lossy media.

Reflection and transmission coefficient for a plane wave normally impinging on a single planar interface.

Script to evaluate the impedance and the reflection coefficient of a load connected to a transmission line. Definition, implementation and use of function. Automatic reporting. Debugging. Use of 'if','switch', 'while'and 'for' instructions. Code optimization by using functions inside a 'for' loop. Use of a 'cell' element for defining the legend.

 

ELECTRON DEVICES

The course describes the physics of the fundamental properties of the electron devices that represent the building blocks of modern electronic circuits and systems.

The main program topics are:
a) basic introduction to: quantum mechanics, statistical physics (Fermi-Dirac statistics) and solid state physics (Drude model, band structure);
b) main concepts of electrical transport in semiconductors (electron and hole concentration, doped semiconductors, drift and diffusion current, equilibrium conditions, generation and recombination, continuity equation);
c) detailed description of the physics, operation and fabrication of pn junctions (diodes): potential and electric field behavior, equilibrium conditions, biased conditions, demonstration of the current expressions, small-signal equivalent circuit, control charge model, reverse bias conditions;
d) detailed description of the physics, operation and fabrication of bipolar effect transistors (BJT): charge control model, demonstration of the Ebers-Moll equations and circuit, input and output characteristics, small-signal equivalent circuit;
e) detailed description of the metal-oxide-semiconductor (MOS) capacitor: band structure, distribution of the voltage difference, threshold voltage, charge behavior, capacitance-voltage curves;
f) detailed description of the physics, operation and fabrication of metal-oxide-semiconductor (MOS) field-effect transistor transistor: dependence of the threshold voltage on the voltage between source and bulk, demonstration of the output characteristics, body effect, small-signal equivalent circuit, short-channel effects.
