This is a 2D schematic + response-curve view of the same on-chip nanoinductor: instead of orbiting a 3D render, you read the device the way an RF engineer reads a datasheet — a cross-section diagram plus a live frequency sweep.
L = K1·μ0·N²·d_avg / (1 + K2·ρ) (planar, modified Wheeler)
L = μ0·N²·A / l_coil (vertical solenoid)
δ = √(2ρ_Cu / (ω·μ0)), R_ac ≈ R_dc·max(1, t/2δ)
Q = ωL / R_ac, f₀ = 1 / (2π√(LC_parasitic))
The top panel draws the coil itself: the planar spiral in true top-down plan view with current-flow dots following its own r(θ) equation, or — for the vertical solenoid — the classic textbook cross-section: turns as alternating ⊗/⊙ current-direction dots either side of the axis, with the on-axis field computed turn-by-turn from the single-loop Biot–Savart law and drawn as field lines whose spacing encodes the summed field strength.
The bottom panel sweeps drive frequency from 1 MHz to 20 GHz at the current geometry and plots Q(f) and R_ac(f) directly — a Bode-style response curve, not a rendering of the device — with a marker at the slider's frequency and a dashed line at the self-resonant frequency f₀ where the parasitic shunt capacitance takes over.
- Coil structure — switch the top panel between the flat spiral plan view and the solenoid cross-section.
- Turns / diameter — feed the same Wheeler/solenoid inductance formulas as the 3D version; redraws both panels.
- Drive frequency — moves the marker along the live Q/R_ac sweep and sets the skin-effect resistance.
