A new varactor model based on the BSIM3v3 model (Berkeley short-channel IGFET model) is presented for the first time to model the behaviour of a silicon-based metal-insulator semiconductor varactor under different bias conditions and operating frequencies.

A General and Efficient Framework for the Rapid Design of Miniaturized, Wideband, and High‐Bit RIS
A general and efficient framework is proposed for the rapid design of high‐performance reconfigurable intelligent surfaces (RISs). This framework integrates advanced antenna design techniques and incorporates various load types, quantities, and values to achieve the design of high‐performance RISs.

Circuit modeling of a MEMS varactor including dielectric charging dynamics [PDF]
Electrical models for MEMS varactors including the effect of dielectric charging dynamics are not available in commercial circuit simulators. In this paper a circuit model using lumped ideal elements available in the Cadence libraries and a basic Verilog-

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Harmonic Generation by Nondegenerate P-N Junction Varactor Diodes
This paper deals with the large-signal analysis of nondegenerate p-n junction varactor diodes. Expressions are obtained for the harmonics of the varactor diode current when driven by a sinusoidal voltage signal. The special case of relatively small input

A Tunable Dual-Band Bandpass-to-Bandstop Filter Using p-i-n Diodes and Varactors
In this paper, a tunable dual-band bandpass-to-bandstop filter and its analysis are proposed. The bandpass-to-bandstop transformation could be obtained by changing the state of the p-i-n diode.
