Three volumes, from electrical foundations to nanoelectronics.
Choose a volume first. Each volume opens a real table of contents: foundations and notation, circuit dynamics and electronic systems, then semiconductor and nanoscale physics.
- I
Electrical foundations, circuit analysis, signals & measurement
Start from charge, voltage, current, Ohm and Kirchhoff before moving to network theorems, signals and instruments.
This volume starts at true introductory level. It builds electrical quantities and sign conventions first, then resistive DC networks, Kirchhoff's current law and Kirchhoff's voltage law, nodal and mesh analysis, sources and superposition. Thévenin/Norton only appears after that foundation, followed by measurement, signals, phasors, AC response and oscilloscope practice.
Open volume → - II
Circuit dynamics, analog electronics, electromagnetics & RF
From RC/RLC and transistor circuits to E/B fields, Maxwell, waves, transmission lines, waveguides and S-parameters.
This volume first treats energy-storage dynamics and analog circuits, then builds the RF/microwave bridge from field physics rather than from isolated formulas: electrostatics, magnetostatics, Maxwell equations, electromagnetic waves, distributed circuits, waveguides, two-port descriptions, S-parameters and measurement.
Open volume → - III
Semiconductor physics, quantum devices & nanoelectronics
From crystal bands and device electrostatics to quantum confinement, material response, plasmons and THz nanoelectronics.
This volume reuses the circuit and electromagnetic foundations to derive nanoscale behaviour from solid-state, semiconductor, quantum and many-body physics. It explicitly reconnects Maxwell/material response to conductivity, permittivity, Drude/Lorentz models, dielectric response, RPA, plasmons and THz devices.

Progress is demonstrated through calculations, designs, measurements, reviews and reproductions.
Real experiments
Claims carry evidence.
A measurement is more useful when the raw file, calibration, method, conditions and interpretation travel with the number.
Simulation
Backed by a reproducible model or circuit run.
Experimental
Supported by instrument data and measurement conditions.
Reproduced
Independently repeated by another member.
MAJAL × AoN
The simulator becomes the laboratory.
Open an exercise in MAJAL, test a design, verify engineering constraints and later publish or fork the result back into the community.
